The problem

MTTR is mostly waiting

Attackers can weaponize a known vulnerability in days. Remediation usually takes weeks, and very little of that time is spent writing code.

Most of it is waiting. Waiting for someone to confirm the finding is real. Waiting to work out who owns it. Waiting for a developer with time to write the fix, then for CI to pass, then for a reviewer, then for someone to notice the PR has gone stale.

Every one of those handoffs needs context about your organization, and today a person supplies it by hand, for every finding. That's the MTTR your program is measured on.

The outcome

What changes with Nullify

Urgent findings start first

Triage separates severity from priority, so a reachable, internet-facing flaw outranks a critical-rated one in dead code.

The fix arrives with the finding

Autofix writes a minimal, root-cause patch and validates it against your build before the PR opens.

It goes to someone who can take it this week

Nullify routes each PR to the owner from CODEOWNERS and commit history, and balances by review load and capacity.

Nobody babysits the PR

When a check fails, Nullify reads the CI logs and pushes follow-up commits until it passes.

Escalation runs on the SLA clock

Stalled PRs and tickets are escalated in Slack with the finding, the risk and the SLA stated.

You can see MTTR move

Program reporting tracks MTTR and SLA compliance by team.

How it works

Three steps, inside the workflow you already have

Prioritize by real risk

Findings are scored continuously on reachability, exploitability, business context and confidence. Actively exploited vulnerabilities and zero-days affecting your stack jump the queue.

Fix and route in one step

Autofix opens a build-validated pull request in GitHub or GitLab and routes it to the commit author, then CODEOWNERS, then the wider team.

Chase it to merge

Nullify fixes CI failures, nudges reviewers on stale PRs and escalates in Slack before the SLA slips. Your developers approve every merge.

FAQ

Frequently asked questions

What is MTTR in vulnerability management?

Mean time to remediate (MTTR) is the average time between a vulnerability being found and the fix being in place. Security teams usually track it by severity, against an SLA for each level.

Why is MTTR so high for critical and high-severity findings?

Usually because of handoffs, not hard fixes. Each finding waits for validation, an owner, a developer with time, a passing build and a reviewer. Severity labels don't help when every finding looks critical and nobody knows which one to start with.

How does Nullify measure MTTR?

Security Program Management reports MTTR alongside current finding counts, campaign progress, per-team progress and SLA compliance, so you can see where time is lost.

What happens when a security fix stalls in review?

Nullify notices the silence, nudges the reviewer and refreshes the branch. If the SLA is about to slip, it escalates to the right person in Slack with the finding, the risk and the fix attached.
