August 2026. Patch management is not an IT chore — it is among the most examined controls at ISO 27001 surveillance. Auditors pick a CVE from the news and ask: when scanned, when patched, who approved?
SLAs that work for SMEs
- critical: 7 days (internet-facing);
- high: 30 days;
- medium: 90 days or next maintenance window;
- exceptions: risk acceptance in management review.
Evidence
Scan reports, tickets, change records. Link to ISMS and vulnerability policy. Cloud posture tools export monthly to evidence folder.
In 2026 unpatched critical CVEs on admin VPNs are a common major finding. MFA without patch does not help.
What to do this week
Pick one concrete action from this article, assign an owner and add it to your risk or improvement register with a deadline. Share briefly in team meetings so compliance is something the line recognises. Repeat quarterly in management review so leadership sees progress, not only intent.

Evidence and governance
Record who owns the measures in this article and how you prove operation in the sample period — logs, tickets, approved changes or exercise reports. Certification bodies and chain partners do not accept intent without samples. Link evidence locations to your SoA or control plan so internal and external audit use the same sources.
Chain and contracts
Many 2026 requirements come via customers, not only formal law scope. Align contract SLAs with your ISMS: incident notification, audit rights, patch timelines and exit. Document where contract is stricter than internal policy — management review must explicitly accept that gap or plan investment.
Continual improvement
Plan a short quarterly review: what worked, which near-miss stood out, which control needs extra attention? Record three improvement actions with owners — that is what ISO 27001, NIS2 and GDPR supervision want to see: PDCA in practice, not paper only.
Knowledge base and readiness
