Under Attack?
Under Attack? No worries, we'll help!
Most basic protection tools rely heavily on known signatures — which works fine until something new shows up. That’s where PhantomGuard steps in. By combining traditional detection with cloud-based analysis, it can spot new and unknown threats in real time without slowing anything down locally.
DDoS Mitigation
PhantomGuard CDN is built to keep your applications online even during heavy attacks. It doesn’t just block traffic blindly — it focuses on filtering out the bad while letting real users through without friction.
What it does well
Stateful request tracking
Instead of treating every request the same, PhantomGuard keeps track of how traffic behaves over time. That makes it much better at telling the difference between a real user and something suspicious, while keeping false positives low.
JavaScript Proof-of-Work challenge
When needed, PhantomGuard can ask clients to complete a small computational task before accessing your site. It’s lightweight for real users but slows down bots enough to make a difference during an attack.
Behavioral analysis
Traffic is constantly monitored for patterns. If something starts to look off — spikes, unusual request flows, automation signals — it reacts quickly and adjusts protection on the fly.
A note on JA4 fingerprinting
PhantomGuard also uses JA4 TLS fingerprinting as an additional signal. It looks at how a client handles TLS (things like cipher suites, extensions, and protocol behavior) to help identify bots and automated tools more reliably than simple IP or user-agent checks.
All of this works together to give you solid, adaptive protection without making things harder for legitimate users. It’s not just about blocking traffic — it’s about keeping your service usable while attacks are happening.
