Which cybersecurity platform is best for small IT teams?
For teams of 5–25 people managing their own security without a dedicated SOC, the answer depends heavily on your stack, your expertise, and how much hands-on time you can realistically commit.
Here's the short version:
- SentinelOne — best for autonomous protection with minimal management overhead
- CrowdStrike — best for teams with an MSP partner or some security expertise
- Microsoft Defender — best if you're already deep in the Microsoft 365 ecosystem
All three score at the top of Gartner's EDR Magic Quadrant, but the differences matter a lot at your scale.
The pricing reality in 2026
Cost is always a factor for smaller teams. Here's what you're actually looking at per endpoint per year:
- Microsoft Defender for Endpoint: roughly €36–60 via M365 licensing — the cheapest entry point by far
- SentinelOne Singularity Control: around €80 per endpoint annually
- CrowdStrike Falcon Pro: €100+ per endpoint, more for enterprise tiers
For a 10-person IT consultancy in Belgium or the Netherlands, that's the difference between ~€600 and ~€1,000+ per year. But the real ROI question isn't the license cost — it's what a single prevented ransomware incident saves you. Industry estimates put the average SMB incident cost at €50,000 or more when you factor in downtime, recovery, and reputational damage.
Why SentinelOne stands out for lean IT teams in 2026
If your team doesn't have a dedicated security analyst checking dashboards all day — and most 10–20 person service companies don't — SentinelOne's autonomous AI model is a genuine differentiator.
The core advantage is its on-device AI engine, which means protection doesn't depend on a cloud connection. For consultants working on trains between Brussels and Amsterdam, or remote team members on unreliable connections, this matters more than vendor marketing usually admits.
What makes SentinelOne particularly compelling for small teams:
- Automatic ransomware rollback — if an attack gets through, the platform can reverse encrypted files in minutes without manual intervention
- Single agent deployment — covers Windows, macOS, and Linux uniformly, which matters if your team uses a mix of devices
- Storyline forensics — gives you a visual timeline of any attack, so even non-security staff can understand what happened
- In MITRE ATT&CK evaluations, SentinelOne consistently outperforms Microsoft Defender, which logged 24 missed detections in recent rounds
One Dutch IT consultancy with 15 employees (cited in security community reviews) reported rolling back a ransomware attack in under two minutes, with offline laptops protected throughout. Their assessment: "Works without a SOC team." That's the pitch for small businesses.
Deployment time: under an hour via automated setup. Start with a 30-day free trial at sentinelone.com to test on 5–10 endpoints before committing.
When CrowdStrike or Microsoft Defender makes more sense
SentinelOne isn't the right answer for every team. Here's when the other two win:
CrowdStrike Falcon — for teams with MSP support
CrowdStrike's global threat intelligence telemetry is genuinely world-class. If you work with a managed security provider, Falcon's data enriches their detection capability significantly. A Belgian service bureau with 20 staff used Falcon Pro with an MSP retainer and reduced security alerts by 80% — the combination of CrowdStrike's intel and managed response made the difference.
The catch: CrowdStrike is cloud-dependent for many of its best features, and it rewards teams who invest time in the platform. Without an MSP or someone who knows what they're doing, you'll underuse what you're paying for.
Best fit: teams that already have an MSP relationship or a dedicated IT security person on staff.
Microsoft Defender — for Microsoft-heavy stacks
If your team runs on Microsoft 365, Azure AD, and Intune, Defender for Endpoint is the path of least resistance. No agent install needed on Windows devices, native integration with your existing admin console, and the lowest cost per user of any enterprise-grade EDR option.
The limitations are real though:
- Weaker on macOS and Linux — if your team uses mixed devices, you'll feel the gaps
- Multiple consoles for full XDR capability — the unified experience requires additional licensing
- Score of 4.4/5 on Gartner versus 4.8/5 for both SentinelOne and CrowdStrike
A practical workaround: layer Defender with Huntress (around €39/endpoint) for 24/7 managed detection. Several US and European SMBs have used this combination effectively, and it keeps costs down while adding real SOC capability.
How to choose: a practical decision framework
Don't overthink this. Answer these four questions:
- Do you use Microsoft 365 heavily? If yes, start with Defender — it's already partially there.
- Do you have mixed OS (Windows + Mac + Linux)? SentinelOne handles this cleanly; Defender struggles.
- Do you work with an MSP? CrowdStrike Falcon with managed detection is worth the premium.
- Are your team members often offline or remote? SentinelOne's on-device AI is the clear winner here.
For most IT and cybersecurity firms and consulting businesses in Belgium and the Netherlands — where hybrid work is standard and Microsoft 365 adoption is high — a combination of Microsoft Defender as a baseline plus SentinelOne for critical endpoints is a cost-effective approach that doesn't require full-time security management.
Practical next steps:
- Audit your endpoints — note Windows/macOS/Linux split
- Run a 30-day free trial of SentinelOne alongside your existing setup
- Check MITRE ATT&CK evaluations to compare detection rates with your own threat profile

Getting your cybersecurity right also reflects on your credibility with clients. If you're a small IT or security consultancy, your own security posture is part of your brand — it's one of the first things enterprise clients scrutinize.
Want to make sure your website reflects that level of trust? At Luniq, we build websites specifically for IT and cybersecurity firms that need to communicate expertise and credibility to their ideal clients. Let's talk about what that looks like for your team.
