BEST ANTIVIRUS FOR SMALL BUSINESS — DEFENDER vs BITDEFENDER vs ESET vs SOPHOS vs SENTINELONE.

WHAT “ANTIVIRUS” ACTUALLY MEANS IN 2026.

The word “antivirus” meant something specific in 2005 — a desktop application that scanned files against a signature database of known-bad malware. That category effectively no longer exists as a standalone product for businesses. What's sold as “antivirus” in 2026 is a business endpoint protection platform: a cloud-managed agent on every workstation and server that combines traditional signature scanning, behavioral analysis, machine-learning detection, exploit prevention, ransomware rollback, and centralized policy management. The category has been renamed several times along the way — EPP (Endpoint Protection Platform), NGAV (Next-Generation Antivirus), EDR (Endpoint Detection and Response), XDR (Extended Detection and Response). The product on the endpoint is roughly the same thing.

This matters because the search query “best antivirus for small business” still gets typed thousands of times a month, even though the underlying need is broader than “signature-based file scanning.” A business owner asking that question usually means: what endpoint protection product should I buy so my employees' laptops don't become a ransomware incident? The answer is a modern endpoint protection platform, with antivirus as one capability among several.

This guide treats the categories together because the products do. Every platform covered here — Microsoft Defender for Business, Bitdefender GravityZone, ESET PROTECT, Sophos Intercept X, SentinelOne — combines traditional antivirus signature scanning with behavioral EDR detection in a single agent. Buying “just antivirus” without the behavioral layer is genuinely difficult to do in 2026, because the major vendors no longer ship that as a separate SKU. You get the modern stack by default.

For the broader EDR-only discussion (which omits the lighter-weight vendors and focuses on the four most enterprise-leaning platforms), see our companion EDR Vendor Comparison pillar. The current guide is the broader “best antivirus” entry point for SMB owners still using the older category vocabulary.

WHY CONSUMER ANTIVIRUS FAILS BUSINESS USE.

Walk into a Florida small business with 12 employees and there's a non-trivial chance you'll find a mix of: the free Windows Defender that came with Windows 11, an expired retail Norton 360 box from 2022 that nobody renewed, a personal Avast Free that one employee installed because they were used to it at home, and a McAfee trial that came preloaded on a Dell laptop and was never licensed. That mix is not a security posture — it's a series of un-managed personal-tier products with no central visibility, no policy enforcement, no audit trail, and in several cases a license violation.

The gap between consumer and business endpoint protection lives in five places:

• Central management. Business platforms have a cloud console where one administrator can see every endpoint, push policy, force remediation, and pull reports. Consumer antivirus has no such console.
• Audit trail. Business platforms log every detection, response, and policy change with timestamps and operator identity. That log is what HHS OCR, the FTC, PCI assessors, and cyber-insurance underwriters want to see. Consumer antivirus may have local logs but no centralized retention.
• Policy enforcement. Business platforms can force scan schedules, prevent user disable, lock exclusion lists, and enforce update cadence across every endpoint. Consumer antivirus lets the end user disable it whenever they want.
• Licensing. Most free or consumer antivirus EULAs prohibit business use — Avast Free, AVG Free, Avira Free, the free tier of Bitdefender, and many others are licensed for personal non-commercial use only. Deploying them on business endpoints is a license violation that can also void cyber-insurance coverage.
• Support contract. Business platforms have a vendor support contract — 24/7 break-glass, technical account manager, SOC integration support. Consumer antivirus has a forum.

For a sole proprietor on a single laptop, free or consumer antivirus is genuinely adequate. For a business with multiple employees, customer data, regulatory exposure, or a cyber-insurance policy, none of those five gaps is acceptable. The cost of a business-tier platform is small relative to one ransomware incident, one HIPAA breach notification, or one cyber-insurance non-renewal.

THE 5 PLATFORMS THAT COVER THE SMB MARKET.

The business endpoint protection market is crowded — independent analyst firms typically list 30+ named vendors at any given time. But for the small business segment (5-100 endpoints, North Central Florida) five vendors cover the overwhelming majority of deployments and remaining categories of need:

• Microsoft Defender for Business: The default for any SMB on Microsoft 365 Business Premium. Bundled with the M365 license; tight integration with the rest of the Microsoft ecosystem; most-deployed business antivirus on US small-business endpoints in 2026.
• Bitdefender GravityZone Business Security: The most popular dedicated SMB antivirus platform outside the M365 bundle. Consistently top-tier in independent test results, broad OS coverage, transparent SMB pricing.
• ESET PROTECT: The long-running SMB favorite. Lightweight agent footprint, low false-positive rate, mature multi-tenant management, particularly strong in Europe and increasingly common with US SMBs.
• Sophos Intercept X: The MSP-friendly option. Multi-tenant Sophos Central console, CryptoGuard ransomware rollback, synchronized security with the Sophos firewall line; popular with MSPs serving SMBs.
• SentinelOne: The platform you choose when traditional AV isn't enough — heavy compliance environments, advanced behavioral detection requirements, automated ransomware rollback, or Mac/Linux-heavy shops where the lighter-weight vendors don't cover the OS mix.

Other platforms you may encounter — CrowdStrike Falcon, Trend Micro Apex One, Kaspersky Endpoint Security (still common outside the US but increasingly avoided in regulated US environments after federal advisories), Webroot, Malwarebytes for Business, Huntress — are all legitimate platforms with their use cases. CrowdStrike specifically is covered in our EDR pillar because it's primarily an enterprise-tier offering with an SMB tier (Falcon Go) on top. For most North Central Florida SMBs, the five platforms above are the practical short list.

The remainder of this guide covers each of the five in depth, then the 10 evaluation criteria that pick between them, real per-endpoint pricing, the audit-failure scenarios that rule out the consumer alternatives, and where Simply IT lands by default.

MICROSOFT DEFENDER FOR BUSINESS: THE M365 DEFAULT.

Microsoft Defender for Business is Microsoft's endpoint protection platform for the SMB segment, scaled down from the enterprise Defender for Endpoint product. It's the most-deployed business antivirus on US small-business Windows endpoints in 2026, driven primarily by the fact that it's bundled with Microsoft 365 Business Premium at no incremental cost. For an SMB already on Business Premium, deploying Defender for Business is the path of least resistance and the lowest total cost of ownership.

Strengths: Native integration with the rest of M365 — Conditional Access policies in Entra ID, Intune device management, Defender for Office 365 email signals, Microsoft 365 Unified Audit Log — all flow into the same Defender portal at security.microsoft.com. The vulnerability management capability (which is a paid add-on at most competitors) is included. Detection quality has reached parity with the dedicated SMB vendors for the threat patterns that small businesses actually face. Microsoft's threat intelligence team has the broadest signal in the industry — billions of M365 endpoints reporting telemetry globally.

Weaknesses: Mac and Linux coverage is functional but trails the dedicated cross-platform vendors. The reporting and alert-tuning interfaces are functional but not as polished as Bitdefender or SentinelOne. Standalone Defender (without the rest of M365) lacks the integration story that makes the platform compelling — the right context for Defender is “the SMB is already on or moving toward M365 Business Premium.”

Pricing: Defender for Business standalone is roughly $3 per endpoint per month. The way most Florida SMBs consume it is bundled inside Microsoft 365 Business Premium ($27/user/month), which also includes the full M365 productivity stack, Intune device management, Entra ID Premium, and Defender for Office 365 Plan 1. At Business Premium pricing, Defender for Business is effectively a zero-incremental-cost feature. For nonprofits, M365 Business Premium nonprofit pricing is $6/user/month — making the math even more lopsided.

BITDEFENDER GRAVITYZONE: THE SMB WORKHORSE.

Bitdefender GravityZone Business Security is the dedicated SMB endpoint protection platform that's most likely to show up on a head-to-head shortlist against Microsoft Defender for Business. The Romanian-founded vendor has been a fixture at the top of independent antivirus testing — AV-Comparatives, AV-Test, SE Labs — for over a decade. The SMB tier (GravityZone Business Security) is priced and packaged for organizations under 100 endpoints, with higher tiers (Business Security Premium, Business Security Enterprise) available as the deployment grows.

Strengths: Consistently among the highest detection rates and lowest false-positive rates in independent testing. Broad OS coverage including Windows, macOS, Linux, and mobile (iOS, Android). The agent is well-engineered and has a noticeably lighter system impact than several competitors. The GravityZone cloud console is one of the cleaner SMB management interfaces on the market — multi-tenant for MSPs, single-tenant for direct customers, with reporting that's genuinely usable instead of just present. Strong ransomware-specific protections including process behavior monitoring and tamper-proof backup of recent files.

Weaknesses: Standalone vendor relationship — separate billing, separate console, separate support — versus the bundled-in-M365 path with Defender. M365 integration exists (Conditional Access, Entra ID identity signals) but requires manual configuration; nothing flows for free the way it does with Defender. The tier-naming convention (Business Security vs Business Security Premium vs Enterprise vs Cloud Workload Security) can be confusing for first-time evaluators.

Pricing: GravityZone Business Security runs roughly $4-7 per endpoint per month at SMB volumes, with the Premium tier adding EDR and patch management for $6-9. Pricing scales meaningfully with volume — 5-endpoint pricing differs from 50-endpoint pricing. Annual commitments are standard but month-to-month is available. For an SMB that's not on M365 Business Premium, or that has heavy Mac/Linux exposure where Defender is weaker, Bitdefender is usually the strongest dedicated alternative.

ESET PROTECT: THE LIGHTWEIGHT SPECIALIST.

ESET PROTECT is the SMB endpoint protection platform that built its reputation on agent efficiency. Originally NOD32 in the late 1990s, ESET has been a fixture of the European SMB market for decades and has steadily grown in US small-business deployments. The platform's defining characteristic is how little system impact the agent has — endpoint scans and real-time protection run with materially less CPU, memory, and disk overhead than several of the heavier competitors. For older hardware, low-spec laptops, or environments where end users are sensitive to performance overhead, ESET is often the strongest fit.

Strengths: The lightest agent footprint in the comparison set. Very low false-positive rate — ESET historically scores at or near the top of false-positive metrics in independent tests. Mature multi-tenant ESET PROTECT Cloud console for MSPs. Full disk encryption, mail security, and server protection available as add-on modules. ESET also has strong specialized products for retail and point-of-sale environments, which fit some Florida SMB use cases (restaurants, small retail) that the broader platforms don't address as directly.

Weaknesses: EDR capability (ESET Inspect, the EDR module) is a paid add-on rather than included by default — for full behavioral detection you're on PROTECT Advanced or PROTECT Complete, not PROTECT Entry. Brand recognition in the US business market lags Defender, Bitdefender, and Sophos; some US cyber-insurance underwriter questionnaires will name those competitors but not ESET, which means the broker may need to confirm acceptance. M365 integration is limited compared to Defender.

Pricing: ESET PROTECT Entry runs $3-5 per endpoint per month, Advanced $5-8, Complete $7-10. The Entry tier is genuinely competitive on pure antivirus capability against more expensive competitors; the Advanced and Complete tiers (which add EDR, full disk encryption, vulnerability and patch management) are where most regulated-industry SMBs end up. Annual licensing is standard.

SOPHOS INTERCEPT X: THE MSP PICK.

Sophos Intercept X is the endpoint protection platform that many MSPs adopted earliest and continue to deploy by default. The Sophos Central management console is multi-tenant by design — one MSP technician can manage Sophos across dozens of client tenants from a single portal — which makes operational economics attractive for the MSP channel. CryptoGuard, Sophos's ransomware-rollback technology, has a strong real-world track record going back over a decade. The platform also has a managed detection and response add-on (Sophos MTR / Sophos MDR) that bundles human SOC coverage at a price point that's often more accessible than third-party MDR procurement.

Strengths: Clean MSP-oriented management. CryptoGuard ransomware-specific protections. Tight integration with Sophos Firewall (the XGS series) for clients running Sophos as a perimeter brand — synchronized security where firewall and endpoint share threat intelligence directly. Strong Server Protection module for SMBs with Windows and Linux server estates. MTR bundle pricing is competitive for SMBs that need MDR coverage but want to avoid the vendor-on-vendor stack complexity of stitching a third-party SOC onto a different endpoint vendor.

Weaknesses: M365 integration is less native than Defender — Sophos is a third-party vendor relative to Microsoft, so signal correlation across email and endpoint requires manual configuration. Detection quality in independent tests has been good but not consistently top of the leaderboard in the most recent 2025-2026 cycles. Mac coverage is improving but still trails SentinelOne and Bitdefender. The console can feel busy for SMBs not used to multi-tenant MSP-style management.

Pricing: Intercept X Advanced runs $5-8 per endpoint per month at SMB volumes. With Sophos MTR Standard (the managed detection and response bundle) the package runs $10-15 per endpoint. Sophos is one of the more negotiable vendors at small-business scale, and the MSP-channel pricing is generally favorable when accessed through a partner like Simply IT. Annual licensing is standard with monthly options at higher rates.

SENTINELONE: WHEN YOU'VE OUTGROWN TRADITIONAL AV.

SentinelOne is the platform you move to when traditional antivirus capability isn't enough — when the compliance environment is heavy (defense contractors, regulated healthcare, audited financial services), when the OS mix is non-Windows-dominant, or when the threat surface includes targeted attacks rather than just commodity malware. Where the previous four platforms in this comparison are best understood as antivirus products with behavioral detection layered on, SentinelOne is best understood as behavioral detection product with antivirus capability included. The architectural difference matters for sophisticated environments.

Strengths: Excellent detection on novel and zero-day threats — the Static AI and Behavioral AI engines run locally on the endpoint, meaning detection and response continue working even when the endpoint is offline. The Storyline feature reconstructs attack chains automatically and can roll back ransomware-encrypted files without backup recovery. Among the strongest cross-platform coverage in the comparison — Windows, macOS, Linux, and a handful of less common platforms are all well-supported, not afterthoughts. Vendor-neutral — works equally well on M365, Google Workspace, hybrid, or no cloud productivity platform at all. The Singularity platform extends beyond endpoint into identity threat detection, cloud workload protection, and data security.

Weaknesses: Standalone vendor relationship — separate billing, console, support. Pricing is meaningfully above Defender for Business if the client is already on M365 Business Premium (where Defender is essentially free). Tier-naming (Core, Control, Complete, Commercial, Enterprise) can be confusing, and the right tier for an SMB is rarely the entry-level one. The platform is more sophisticated than many smaller SMBs need — paying for advanced features they won't consume.

Pricing: SentinelOne Core runs $5-7 per endpoint per month at SMB volumes; Control adds device control and firewall control for another $2/endpoint; Complete adds threat hunting and forensic features for another $3-4/endpoint. Most regulated-industry SMBs we deploy SentinelOne for end up on Control or Complete. Vigilance Respond (managed SOC) is a separate add-on. Pricing is negotiable at 50+ endpoints. For most Florida SMBs, SentinelOne is the secondary recommendation rather than the default — but where it fits, it's a meaningfully more capable platform than the alternatives.

THE 10 EVALUATION CRITERIA FOR SMBs.

Most antivirus procurement decisions get made on brand familiarity or price. The decision is materially better if it accounts for these ten criteria — the ones that actually predict outcomes once the product is deployed and in daily operation:

1. 01
   Detection Quality in Independent Tests

   AV-Comparatives, AV-Test, SE Labs, and MITRE ATT&CK evaluations publish independent results every quarter. Detection-rate gaps between top-tier vendors are smaller than marketing suggests, but the bottom of the pack is genuinely worse. Bitdefender, ESET, and SentinelOne consistently score near the top across cycles; Defender for Business has closed the gap dramatically since 2023.
2. 02
   False-Positive Rate

   A platform that flags every legitimate business application is functionally unusable — end users learn to dismiss alerts. ESET historically wins on false-positive metrics; Bitdefender and Defender are close behind.
3. 03
   System Impact (Performance Overhead)

   Real-time scanning, behavioral analysis, and EDR telemetry all cost CPU, memory, and disk I/O. ESET is the lightest in the comparison; Defender is well-tuned for Windows; the heavier behavioral engines (SentinelOne, Sophos) have improved but still impact older hardware more noticeably.
4. 04
   OS Coverage (Windows / Mac / Linux / Mobile)

   Defender is strongest on Windows. SentinelOne and Bitdefender have the strongest cross-platform story. Mac-heavy creative shops, Linux server environments, mixed shops, and BYOD-heavy organizations should weight OS coverage heavily.
5. 05
   Management Console Quality

   If you or your MSP will be in the console daily, the UX matters. Bitdefender GravityZone and SentinelOne consoles are widely admired; ESET PROTECT Cloud is functional; Sophos Central is MSP-friendly multi-tenant; Microsoft Defender portal is feature-rich but Microsoft-traditional in feel.
6. 06
   Microsoft 365 Integration Depth

   Defender for Business has the deepest integration: Conditional Access, Intune, Entra ID, Defender for Office 365, Unified Audit Log all in one portal. Standalone vendors require manual configuration to connect equivalent signals. For SMBs heavy on M365, this often dominates other criteria.
7. 07
   Cyber-Insurance Carrier Acceptance

   Underwriter questionnaires now ask whether next-generation antivirus / EDR is deployed. All five platforms in this guide qualify on every major carrier's questionnaire, but some carriers have named partnerships with specific vendors that affect premiums. Ask your broker.
8. 08
   Compliance and Regulatory Fit

   HIPAA-aligned BAA (Microsoft signs a BAA covering Defender for Business; the other vendors will sign BAAs on commercial agreements). FedRAMP authorization for federal-adjacent work (Microsoft and SentinelOne are strongest here). CMMC alignment for defense contractors (Defender via M365 GCC; SentinelOne has gov-cloud options).
9. 09
   MDR Availability and Pricing

   Software without a human watching it produces alerts nobody reads. Each platform has a managed-service option — Defender Experts, Bitdefender MDR, ESET MDR, Sophos MTR, SentinelOne Vigilance. Or an MSP like Simply IT provides equivalent coverage as part of the standard engagement.
10. 10
    Vendor Stability and Support Quality

    Endpoint protection is a multi-year commitment. Vendor financial health, support ticket quality, and recent incident track record all matter. Avoid vendors recently merged, recently spun out, or under federal advisory restriction. Ask for references at your size band before signing.

The right vendor is rarely the same answer across all 10 criteria. The decision is a weighted-average problem, not a single-criterion ranking. For most Florida SMBs on M365 Business Premium, Defender for Business wins more criteria than it loses — which is why it's our default — but the Bitdefender and ESET alternatives win on enough criteria for specific business profiles that they earn the secondary slots.

PRICING REALITY: PER-ENDPOINT PER-MONTH IN 2026.

Published vendor pricing pages are rarely the actual price an SMB pays. Here's the realistic 2026 pricing for North Central Florida small businesses in the 5-100 endpoint range:

• Microsoft Defender for Business (standalone): roughly $3/endpoint/month.
• Microsoft Defender for Business (via M365 Business Premium $27/user): effectively zero incremental cost — Defender is part of the bundle along with M365 productivity apps, Intune, Entra Premium, Defender for Office 365 Plan 1.
• Bitdefender GravityZone Business Security: $4-7/endpoint/month, Premium tier $6-9.
• ESET PROTECT Entry / Advanced / Complete: $3-5 / $5-8 / $7-10 per endpoint per month.
• Sophos Intercept X Advanced / + MTR Standard: $5-8 / $10-15 per endpoint per month.
• SentinelOne Core / Control / Complete: $5-7 / $7-9 / $9-12 per endpoint per month.

For nonprofits, Microsoft 365 nonprofit pricing dramatically changes the math: M365 Business Premium nonprofit pricing is $6 per user per month — making the M365-bundled Defender for Business path nearly unbeatable on cost. Most Florida nonprofits we work with land on Business Premium for the full security stack rather than buying standalone antivirus.

The non-obvious cost line is the human side. Endpoint protection software without someone watching the console is a portal full of alerts nobody reads. Vendor-bundled MDR (Defender Experts, Bitdefender MDR, Sophos MTR, SentinelOne Vigilance) typically adds $5-15 per endpoint per month on top of the license. Third-party MDR (Arctic Wolf, eSentire, Huntress) typically runs $20-40 per endpoint per month. An MSP like Simply IT bundles MDR-equivalent coverage into the managed-IT tiers (Simply Managed $75/user, Simply Secure $125/user, Simply Compliant $150/user per month, no long-term contracts) — that math typically beats stacking standalone vendor licenses plus a separate MDR provider.

For SMBs evaluating purely on license cost, Defender for Business via M365 Business Premium is almost always the winner. For SMBs evaluating on total-cost-of-ownership including human SOC coverage, the right answer depends on whether MDR is sourced from the vendor, a third party, or an MSP.

WHY FREE ANTIVIRUS FAILS BUSINESS AUDITS.

Every Florida small business eventually faces an audit moment — a HIPAA risk assessment, an FTC Safeguards Rule attestation, a PCI DSS self-assessment questionnaire, a cyber-insurance underwriter renewal, a SOC 2 readiness review, or a CMMC pre-assessment. The endpoint protection question always comes up, and the answer “we use the free version of [X]” consistently produces audit findings. The specific failure modes:

• HIPAA Security Rule, 45 CFR 164.308(a)(5)(ii)(B): requires “procedures for guarding against, detecting, and reporting malicious software.” A free consumer product with no centralized detection log, no policy enforcement, and no audit trail does not produce the evidence an HHS OCR investigator expects.
• FTC Safeguards Rule (16 CFR Part 314): requires CPA firms and other financial institutions to implement a written information security program with documented safeguards. Free consumer antivirus produces no documentation suitable for the FTC's expectations of a qualified individual's oversight.
• PCI DSS Requirement 5: requires anti-malware on all systems commonly affected by malware, with active running protection, current signatures, and audit-log retention. Free consumer antivirus typically fails on the audit-log requirement and often on the centralized-management requirement.
• Cyber-insurance underwriter questionnaires: almost universally ask whether “next-generation antivirus / EDR” is deployed to all endpoints with centralized management. Answering “we use free Windows Defender consumer edition” either disqualifies the application outright or drives premium loads.
• Florida Bar Rule 4-1.6 (lawyer cybersecurity): Florida attorneys have an ethical duty to make reasonable efforts to prevent unauthorized access to client confidential information. The Bar's ethics opinions and trend lines make clear that free consumer antivirus is not “reasonable” for a practice handling client confidences.
• EULA license violations: Avast Free, AVG Free, Avira Free, Bitdefender Free, and most other consumer free antivirus EULAs prohibit business use. Running them on business endpoints is a license violation that can void cyber-insurance and create liability exposure if discovered during a breach response.

The dollar gap between free consumer antivirus and business-tier endpoint protection is small — typically $3-10 per endpoint per month. The audit, insurance, and regulatory consequences of running free consumer antivirus on business endpoints are not small. The math always favors deploying business-tier endpoint protection.

If you're reading this and the audit moment hasn't happened yet, do not wait for it to happen. Migration from free consumer antivirus to a business platform takes a few hours per endpoint and produces an audit-ready posture immediately. Migration from a breach incident or a denied cyber-insurance renewal is materially more expensive.

THE SIMPLY IT ANTIVIRUS RECOMMENDATION.

Here's the practical answer. Simply IT's default business antivirus for new managed clients is Microsoft Defender for Business, delivered via Microsoft 365 Business Premium. The reasons stack: it's included in the M365 license most clients already have or are moving toward, the M365 ecosystem integration (Conditional Access, Intune, Defender for Office 365, Entra ID) compounds value, detection quality has reached parity with the dedicated vendors for the threat patterns SMBs actually face, and it eliminates a separate vendor billing and support relationship.

We deploy Bitdefender GravityZone Business Security at clients where the M365 path doesn't fit — heavy Mac populations (creative shops, some medical practices, some legal firms standardized on Mac), Linux server environments where Defender's Linux story is too thin, or organizations that for vendor-neutrality reasons specifically don't want a Microsoft endpoint product. Bitdefender consistently wins on independent test results, has the strongest cross-platform coverage in the dedicated SMB tier, and integrates cleanly into an MSP-managed environment.

We deploy ESET PROTECT at clients with significant older-hardware footprints where agent lightness genuinely matters, or where false-positive rates are sensitive (some manufacturing line-of-business applications, specific point-of-sale environments). ESET is a quieter choice than Defender or Bitdefender — less marketed in the US, but mature, well-built, and the right answer for some profiles.

We deploy SentinelOne at clients where traditional antivirus capability isn't sufficient — defense contractors under CMMC, regulated medical practices with sophisticated threat exposure, financial services firms under SOC 2 audit. The platform is meaningfully more capable on behavioral detection and automated response than the lighter-weight alternatives; the cost premium is justified by the capability premium for those use cases.

Sophos Intercept X we'll deploy when a client specifically requests it, when they have an existing Sophos firewall investment that benefits from synchronized security, or when their existing engagement includes Sophos MTR coverage we're inheriting. We're not religious about any specific endpoint vendor — the right answer is the one that fits the client's situation, not the one we're paid the most to push.

The bottom line for Florida SMBs: in 2026, business-tier endpoint protection is required infrastructure. The default answer for most of you is Microsoft Defender for Business via M365 Business Premium, with Bitdefender, ESET, or SentinelOne as the secondary path where the M365 fit isn't right. If you'd like a vendor-neutral written recommendation specific to your business, get a free Simply IT antivirus scoping call — we'll review your current endpoint protection, your insurance environment, your compliance posture, and your M365 license mix, and give you an honest written recommendation.
