First: stay calm, act fast ✅
A hosting incident can happen to anyone even large platforms. This week, Vercel published a security bulletin about unauthorized access to certain internal systems and shared recommendations for customers.
Most damage doesn’t come from the first alert it comes from waiting too long or not rotating access.
This checklist is designed for small businesses and teams that want to respond quickly, without being security experts.
Rotate keys and secrets 🔑
Treat secrets as “possibly exposed” until proven otherwise:
- API keys and tokens
- database passwords
- third-party integrations (payment, email, analytics, automation)
Best practice:
- rotate the most sensitive keys first
- revoke old tokens/sessions
- document what you changed (so you don’t lose track)
Log out sessions and re-auth users 🔒
If an attacker obtained session tokens or credentials, active sessions can be risky.
Quick actions:
- force logouts where possible
- reset admin sessions first
- ensure only trusted devices remain logged in
Lock down access (2FA + remove unused accounts) 🛡️
This is one of the highest-impact steps:
- enable 2FA on admin accounts (hosting, GitHub, Google Workspace, CMS)
- remove old users, unused accounts, and unknown collaborators
- reduce permissions (least access needed)
If your team is small, keep admin access very limited.
Check logs and recent changes 👀
Look for anything you didn’t do:
- new deployments
- environment variable changes
- redirects or domain changes
- new integrations / webhooks
- unusual logins or new devices
If your provider publishes indicators of compromise (IOCs) or guidance, follow them and compare with your logs.
Verify backups and follow official updates ✅
Backups are your insurance:
- confirm you have recent backups
- test restore if possible (even a small test)
- ensure backups are stored safely (not only in one place)
Also:
- follow the provider’s incident page / security bulletin for updates and recommendations
- keep notes of every action you take (useful later)
A simple team rule that prevents big mistakes 🤝
For 48 hours after an incident:
- verify any “payment change” requests by phone
- double-check emails asking for access, codes, or urgent actions
- slow down approvals and require a second look
Incidents increase scam attempts (attackers often follow the news).
