Network Security

Secure the protocol attackers hide in

Inspect DNS requests in real time, block malicious destinations before connection, and detect phishing, tunneling and crypto-mining hidden in DNS traffic.

The problem

DNS is a blind spot

Attackers exploit DNS because it is rarely inspected, hiding phishing, tunneling and data exfiltration in plain sight.

Malicious domains

Requests to C&C and phishing sites go through before any session is blocked.

DNS tunneling

Data exfiltration hides inside legitimate-looking DNS queries.

Crypto-mining

Mining traffic degrades endpoints and inflates costs, unseen.

Capabilities

Block before connection

Every DNS request is inspected and scored in real time, so malicious destinations are stopped before a session begins.

AI-based phishing protection

Analyze webpage components, domain age, popularity and phishing-toolkit patterns to stop credential harvesting.

FAQ

Common questions

What can DNS Security detect?
Phishing, impersonation, DNS tunneling, crypto-mining and malicious domains, including threats hiding in permitted DNS traffic.
Does it slow down lookups?
No. Inspection happens in real time in the cloud without adding latency.
