The metrics that matter
MTTD: Mean Time to Detect
This measures how long it takes your team to notice that something's wrong, from the moment an issue first appears to the moment someone (or something) flags it. A shorter MTTD means threats are caught while they're still small and containable. A long one means an attacker has had free rein in your environment, sometimes for weeks, before anyone even knew to respond.
MTTR: Mean Time to Respond (or Remediate, or Recover)
MTTR gets used loosely, and that's part of the problem. It can mean time to respond to an alert, time to remediate the underlying issue, or time to fully recover operations. Whichever definition your team uses, the point is the same: once you know about a problem, how fast do you fix it? This is often the single most telling number in the whole report, because detection without fast follow-through doesn't reduce your risk much.
MTTC: Mean Time to Contain
A close cousin of MTTR, it’s worth knowing how long it takes to stop an issue from spreading once it's found, even before it's fully resolved. Useful for ransomware and lateral-movement scenarios specifically, where containment speed often matters more than full remediation speed.
The vanity metrics to watch out for
Not every number that looks good on a slide deck is meaningful. A few common offenders:
- Raw counts of blocked threats or alerts. A bigger number usually just means more noise hit your filters, not that your program is more effective. Without context on what got through, it's not a measure of security posture.
- Number of vulnerabilities patched. Patching 500 low-risk vulnerabilities looks productive, but it says nothing if the 5 critical ones that were exploitable took three months to fix.
- Training completion percentage. Knowing 98% of employees clicked "complete" on a phishing training module doesn't tell you whether anyone's behavior changed. Click rates on your own simulated phishing tests are a far better signal.
- Security spend as a percentage of IT budget. A useful benchmarking data point in the right context, but on its own it measures investment, not outcomes.
Why this matters for your board conversations
Boards don't need a firehose of activity metrics, they need a small number of numbers that answer a real question: are we catching problems quickly, and are we fixing them quickly once we do? MTTD and MTTR (or MTTC, depending on the scenario) do that. Everything else is better used as supporting detail, not headline metrics.
How Aiden helps
Remediation speed is where a lot of security programs lose ground. IT teams usually know what needs fixing, but manually verifying, testing, and deploying patches across every endpoint takes time your MTTR clock doesn't forgive. Aiden helps close that gap by automating Windows endpoint patching, vulnerability remediation, and configuration management, reducing the time between identifying an issue and verifying it's resolved. And since AidenVision provides time-stamped records of remediation activity, that improvement is easy to show, not just claim, the next time the board asks how you're doing.
