VendorVerdict

Your EDR may not offer the same capabilities on every endpoint. That's easy to miss during an evaluation. A vendor can legitimately say: "We support Windows, macOS and Linux." But "supported" doesn't necessarily mean the same security capabilities exist across all three. Microsoft Defender for Endpoint is a useful example. Microsoft's current documentation confirms support for Windows, macOS and Linux. It also shows differences in specific capabilities by operating system. For example: • ASR rules: Windows - not macOS or Linux • Controlled Folder Access: Windows - not macOS or Linux • Exploit Protection: Windows - not macOS or Linux • Device Control: Windows and macOS - not Linux • Network Protection: Windows, macOS and Linux - with Linux currently documented as Preview None of this means Defender is a good or bad choice. That's not the point. The buying question is: Which capabilities influenced your decision and are those capabilities available across the endpoints you actually need to protect? So an EDR evaluation shouldn't stop at: Operating system supported ✓ It should also ask: Required capability supported on that operating system ✓ / ✕ Because a platform can support your Windows, macOS and Linux estate... while some of the capabilities that influenced your decision have different platform coverage. Don't just ask whether your EDR supports your estate. Ask whether the capabilities you're buying support your estate. #CyberSecurity #CISO #EDR #SecurityArchitecture

Most organisations would never let a critical infrastructure change reach every production system at once. So here's a question worth asking when you evaluate EDR: How much control do you actually have over the security product updating your endpoints? Not just the agent version. The content, engine, intelligence and configuration updates underneath it. Before signing, I'd want the evaluation team to be able to answer: • Can updates be staged through test and production groups? • Which updates can we delay and which are delivered automatically? • Can critical servers follow a different release path from user devices? • What rollback options exist? • How quickly can a problematic update be stopped? • Are agent, engine, detection-content and intelligence updates governed differently? This isn't theoretical functionality. Microsoft documents separate Defender update channels, including staged and broad deployment options. Sophos documents staged content updates and controls over when product updates become available. CrowdStrike changed its Rapid Response Content deployment controls following the July 2024 incident. The point isn't that one approach is right and another is wrong. It's that "how does your product update itself?" is part of the security architecture. Yet it rarely gets the same scrutiny as detection rates, integrations or MITRE results. Your EDR has permission to protect thousands of endpoints. Your evaluation should understand exactly how changes reach them. #CyberSecurity #CISO #EDR #SecurityOperations

Every major cybersecurity purchase involves three established roles. Vendors explain their products. Analysts evaluate the market. Procurement manages the buying process. Each plays an important role. We believe there's a fourth role that's largely been left to the buyer. Independent due diligence. Not another product comparison. Independent validation of the commercial, contractual and operational assumptions behind the recommendation. Because some of the biggest risks in a security purchase aren't discovered during the demo. They're discovered during deployment. At renewal. When you try to leave. Or when someone asks: "Why did we choose this vendor?" That's the gap needs closing. Every organisation should understand not just what a product can do, but what the decision to buy it really means over the next three to five years.

One sentence can end an EDR evaluation surprisingly quickly: "We already own Microsoft Defender." Sometimes that's absolutely the right conclusion. But owning a capability and proving it's the right decision are two different things. Before allowing "already included" to settle the evaluation, there are still questions worth answering: Which Defender capability is actually included in our licence? What additional licensing is required for the operating model we want? What will implementation require? What skills will we need internally? What telemetry costs sit elsewhere? What capability are we accepting or giving up compared with the alternatives? And most importantly: Does it fit our environment better? The same principle works in reverse. A specialist EDR vendor shouldn't win simply because it has more capability on paper. Microsoft shouldn't win simply because capability is already included. Both conclusions need evidence. "Already owned" is a licensing fact. It isn't a vendor evaluation. How often does consolidation determine the shortlist before the evaluation has really started? #CyberSecurity #CISO #EDR #MicrosoftSecurity

Here's a question worth asking about your EDR contract: If the vendor causes a major outage, what's the most you can actually recover? We compared the published liability provisions across six major EDR/XDR vendors. The answers vary significantly. Some general liability caps are broadly linked to fees paid. One published position we reviewed was equivalent to around six months of subscription fees, with different treatment for certain privacy/security claims. Microsoft requires you to check the agreement governing your own purchase. Now compare that with the potential impact of a serious endpoint outage. That's the mismatch buyers should understand. The contract doesn't necessarily compensate you for the loss you suffer. It defines the loss the supplier has agreed to be responsible for. Those are very different numbers. Two questions I'd want answered before signing: What's our actual liability cap? And: Is that appropriate for the operational dependency we're creating? Do you know the number in your current endpoint security agreement? #CyberSecurity #CISO #Procurement #CyberRisk

We reviewed the published terms of six major EDR/XDR vendors. One finding stood out: 0 of 6 published a fixed cap on annual renewal price increases. The standard position generally leaves renewal pricing tied to the commercial terms applicable at renewal rather than guaranteeing today's price indefinitely. That's easy to overlook when you're negotiating the initial deal. But think about when your leverage is strongest. Before signature, you have competing vendors, an active sales team and the ability to walk away. Three years later, you have deployed agents, tuned policies, trained analysts, integrations and migration cost. Your negotiating position has changed considerably. Which is why renewal protection isn't something I'd leave until renewal. If predictable pricing matters, negotiate the mechanism while you still have leverage and put it in the Order Form. The headline discount gets attention. The renewal mechanism can matter for much longer. #CyberSecurity #CISO #Procurement #VendorManagement

Every major cybersecurity purchase involves three established roles. Vendors explain their products. Analysts evaluate the market. Procurement manages the buying process. Each plays an important role. But I've realised there's a fourth role that has largely been left to the buyer. Independent due diligence. Not another product comparison. Not another analyst report. Independent validation of the commercial, contractual and operational assumptions behind the recommendation. Because the biggest risks in a security purchase often aren't discovered during the demo. They're discovered months later. At renewal. During deployment. After an audit. Or when someone asks: "Why did we choose this vendor?" That's the gap I believe the industry still needs to close. Not because vendors or analysts are doing anything wrong. Because every organisation deserves to understand not just what a product can do, but what the decision to buy it really means over the next three to five years.
