Multiple defences introduce blind spots
Firewalls, proxies and DNS protection each guard a different layer. Their complexity, integrations and configuration drift leave hidden gaps that attackers can use.
Every security product reports what it blocks. None can report what it misses. Security Gap measures exactly that.
Three tests, every layer
For each malicious domain it finds in your DNS logs, Security Gap simulates a connection in three ways.
Can it get past your gateway?
Tries a direct connection to the malicious domain through your firewall and checks whether it gets through.
Does your proxy stop it?
Sends an HTTP request through your proxy and checks whether its block page comes back or the request reaches our test server.
Does your DNS protection answer?
Queries your DNS server for the domain and checks whether it is blocked or resolves to the domain's real address.
Every gap in one report
See how much malicious traffic got past each layer, and which domains, users and devices were involved.
- Passed all tested controls
- Stopped by at least one control
Share of tested requests each control let through. The firewall gap is what the simulation above measures.
- Firewall gap24%
- Proxy gap22%
- DNS protection gap31%
