Protect what you deploy on Vercel and Netlify.
Every push creates a preview link, every project holds keys, and every function can be called from the internet. BurstLayer keeps an eye on all three.
Shipping ten times a day means ten chances to ship a mistake.
A preview link shared in a chat, a key added to the wrong environment or an API route without a login check can reach the internet in seconds. BurstLayer checks every deploy for these slips.
What goes wrong on deploy platforms
Fast deploys are a gift. These are the mistakes that ride along with them.
Public preview links
Previews of unfinished work, open to anyone who finds the link. We flag them and can switch on protection.
Keys sent to the browser
Secret keys exposed to visitors because of a wrong prefix or setting. We catch them during the build.
API routes without a login check
Server functions that change data without checking who is asking. We point them out.
Bot traffic and scraping
Automated traffic that runs up your bill and copies your content. Network Overwatch filters it.
Risky dependencies
Packages with known flaws in your build. We tell you which ones, and the safe version.
Old team access
Former team members who can still deploy. We list who has access to production.
Every deploy, checked before it goes public.
Each deployment gets the same checks: who can open it, which keys it exposes and which routes it adds. Problems are flagged on the deploy itself.
- Public previews protected with one click

How BurstLayer protects your deploys
The integration watches your projects and deploys. The optional Node.js package adds protection inside your functions.
Checks on every deploy
Every branch and preview is checked the moment it builds.
Preview protection
Turn public preview links into team-only links, automatically or one by one.
Environment key checks
Keys that would reach the browser, or sit in the wrong environment, are flagged.
A firewall at the edge
Attack patterns and bad bots are blocked before your functions run.
Dependency alerts
Packages with known flaws are reported with the safe version to use.
A team access review
See who can deploy to production, and remove people who have left.
