The full Safety Check grades encryption, browser protection, sessions, attack filtering, AI agents, software, third parties, email and reputation, and shows exactly which gaps SENTRA closes.
What you should know.
Why does TLS 1.0 still matter?
TLS 1.0 and 1.1 were retired in 2021 and fail PCI DSS. A server that still accepts them lets an attacker on the network push visitors onto weaker encryption.
What is HSTS?
Strict-Transport-Security tells browsers to use HTTPS for your site every time, so the first request can't be intercepted over plain HTTP.
How does SENTRA help?
SENTRA AI SHIELD terminates TLS 1.2 and 1.3 only, renews certificates automatically, sets HSTS and alerts before anything expires.
