Bottom line up front: if you hold Microsoft 365 E5, you already possess enterprise-grade endpoint protection and should leverage it as your starting point.
For organizations without a dedicated security specialist, Sophos emerges as the most user-friendly platform. Conversely, if you have a Security Operations Center (SOC) and the budget to support it, CrowdStrike is the recommended choice. Beyond these options, the selection becomes a matter of fit based on your specific needs.
Business endpoint protection serves as a crucial shield against malware and attacks targeting laptops, desktops, and servers. It integrates signature matching, behavioral analysis, machine learning, and exploit prevention into a single, centrally managed agent.
Stage 1 — Size Yourself Honestly
The most beneficial first step in your evaluation process is to assess your organization’s current situation accurately. Below is a guide to help you determine your needs:
| Your situation | What you actually need | Our pick |
| Already on Microsoft 365 E5 | Use what you own | Microsoft Defender for Endpoint |
| 25–250 staff, generalist IT | Good protection, easy console | Sophos |
| Mature SOC, funded | Best detection and hunting | CrowdStrike |
| 250–1,000 staff, part-time security | Automation to compensate for headcount | SentinelOne |
| Older hardware, VDI, low budget | Lightest possible agent | ESET |
| Under 25 staff, no IT person | Something that works unattended | Avast Business or Microsoft Defender for Business |
| Value-focused, mixed estate | Solid protection, low cost | VIPRE |
| Heterogeneous estate, limited SOC capacity | Tool-agnostic managed detection and response | Expel |
The honest test: If no one in your organization will check a security console this week, you likely fall into the top two categories. It’s prudent to purchase based on your current reality rather than an idealized version of your organization. An unmonitored premium platform can offer less protection than a well-configured, simpler solution.
Stage 2 — Understand What Has Changed
Antivirus and EDR are now unified under a single agent. Each platform offers prevention and detection-and-response features as licensing tiers on one agent. The pertinent question is not whether to choose antivirus or EDR, but rather which tier to select and whether anyone will utilize the detection capabilities.
Inquire with every vendor about their update staging processes. A significant incident in July 2024, where a faulty content update from a major endpoint vendor led to widespread Windows system failures, underscored the importance of this inquiry. Ensure you can define rollout rings, delay content updates on critical systems, and understand the documented rollback procedure—these have become standard due diligence questions.
Independent tests are invaluable; vendor summaries are not. Organizations like AV-Comparatives and AV-TEST evaluate protection rates and false positives against real-world samples. The MITRE ATT&CK Evaluations reveal what each product detected against specific adversary techniques without scores or rankings. Any vendor claiming to have “won MITRE” has likely fabricated a metric. Always review the raw results.
Servers and Linux are often overlooked. Linux servers are prime targets for ransomware due to their frequent lack of protection. It’s essential to assess coverage depth on your actual server estate, not just on laptops.
Stage 3 — The Eight Picks by Use Case
Best if you already hold Microsoft 365 E5 — Microsoft Defender for Endpoint

Best for: organizations desiring managed detection and response across a heterogeneous security environment without committing to a single XDR platform.
Stage 4 — Deploy Without Breaking Things
One critical rule to remember is to never run two real-time agents simultaneously. During migration, utilize exclusions or execute a hard cutover. Running two products that monitor file access concurrently can severely degrade performance and may lead to mutual quarantining.
Additionally, ensure to activate prevention features. Surprisingly, many deployments remain in detect-only mode indefinitely due to concerns about false positives during the pilot phase, with no follow-up to enable blocking. Establish a timeline for enabling blocking features.
Test the deployment on your line-of-business applications first, as bespoke and legacy applications often generate the most false positives. Conduct the pilot where these applications are utilized, not solely within the IT department.
Define the rollout rings prior to going live. Start with a pilot group, then expand to a broader ring, and finally roll out to the entire organization, allowing for a soak period between each phase. This applies to both agent updates and content updates, reflecting lessons learned from recent years.
Lastly, confirm that your non-Windows coverage functions as expected. Install the solution on actual Macs and Linux servers during the pilot phase, as support depth can vary significantly beyond what datasheets indicate.
Stage 5 — Verify Before You Commit
In your vendor discussions, ask about update staging and rollback procedures. Ensure clarity on rollout rings, content update delays for critical systems, and the documented rollback procedure, including expected duration. This inquiry should be standard for every vendor.
Obtain the tier map in writing, detailing which tier includes EDR, the number of days of telemetry retention, and the costs associated with managed services. Retention length is often a hidden cost in this category.
Check whether your Microsoft licensing already covers you. Defender for Endpoint P2 is included with Microsoft 365 E5. Many organizations inadvertently purchase a third-party platform while already paying for a comparable solution.
Confirm who will respond to alerts. If the answer is nobody, consider opting for a lower EDR tier and allocate the savings towards managed detection and response services. An unmonitored EDR can become an expensive audit log.
Common pitfalls include acquiring premium endpoint protection while neglecting identity and privileged access management—common escalation points for breaches; overlooking Linux servers entirely; and failing to test the response workflow until a real incident occurs.
Situational FAQ
What is the best business antivirus for a small business?
For organizations with fewer than 25 staff and no IT support, Avast Business or Microsoft Defender for Business offer sufficient protection with minimal management requirements. If you already subscribe to Microsoft 365 Business Premium, Defender for Business is included and should be utilized before considering other options.
Is Microsoft Defender good enough for business?
For the majority of organizations, yes. Defender for Endpoint performs competitively in independent evaluations and integrates seamlessly with the Microsoft security stack. Considerations include licensing tier—full EDR capabilities require P2 or E5—and the depth of macOS and Linux coverage compared to Windows, as well as whether consolidating security and productivity under one vendor is acceptable for your organization.
What is the difference between antivirus and EDR?
Typically, they are the same agent offered at different licensing tiers. Antivirus focuses on preventing known and predictable threats using signatures, behavioral analysis, and machine learning. Endpoint detection and response (EDR) records activity, identifies attacker behavior that bypassed prevention measures, and provides tools for investigation and containment. Opt for the EDR tier only if you have personnel available to utilize it.
Do I need endpoint protection on servers and Linux?
Yes. Linux servers are often high-value ransomware targets due to their frequent lack of protection, and a compromised server can cause significantly more damage than a laptop infection. Coverage depth varies widely by vendor, even when Linux support is advertised, so it’s crucial to test on your actual distributions during evaluation.
How much does business endpoint protection cost?
Costs are typically structured per endpoint or per user annually, with tiers determining EDR depth, telemetry retention, and managed services. ESET, Bitdefender, and Microsoft provide list pricing; however, premium cloud-native vendors often operate on a quote basis, with published entry pricing for small businesses. Retention length remains the most significant variable across quotes.
What should I ask every endpoint vendor?
Four essential questions to pose: how do you stage content and agent updates, and can I control the rollout rings; what is the documented rollback procedure and its expected duration; how many days of telemetry does my tier retain; and what is your macOS and Linux capability relative to Windows? These inquiries will help differentiate marketing claims from actual product capabilities.
The Short Version
Begin with your Microsoft licensing—Defender for Endpoint is included in E5 and is genuinely competitive. Purchasing around it should be a deliberate decision rather than an oversight.
Sophos is the optimal choice for the mid-market, where IT generalists are more common than security specialists.
CrowdStrike justifies its premium only when analysts are available to utilize its capabilities; SentinelOne is preferable when automation must compensate for staffing shortages.
ESET excels in lightweight solutions, while Avast Business offers simplicity for very small organizations. Regardless of your choice, always inquire about update staging—a question that has become increasingly vital in this category.
