Encrypted Traffic Hides Malicious Payloads by Default
More than 90% of internet traffic is now encrypted, including attacks. Malware, data theft, and C2 communication pass through TLS undetected. Traditional firewalls struggle without decryption and deep inspection.
Attackers Mimic Legitimate Traffic to Blend In
Threat actors use the same protocols, ports, and behaviors as regular users. Their C2 traffic resembles browser sync, Teams calls, or software updates. This camouflage defeats signature-based detection.
Static Network Segmentation Fails Under Cloud Workloads
Legacy VLANs and firewall rules don’t adapt to ephemeral workloads. Containers and serverless functions spin up and vanish rapidly. Network policies must evolve dynamically with infrastructure.
Free email without sacrificing your privacy
Gmail tracks you. Proton doesn’t. Get private email that puts your data — and your privacy — first.
Geo-Based Blocking Is Easily Bypassed
VPNs, proxies, and cloud relays allow attackers to appear local. Firewalls relying on IP geography are increasingly irrelevant. Adversaries route through compromised SaaS accounts or CDN nodes.
Threat Actors Use DNS Over HTTPS to Obfuscate Calls
DNS queries are encrypted and routed through trusted providers like Google or Cloudflare. Malicious domains hide among legitimate ones. Without DoH inspection, DNS telemetry becomes useless.
Adaptive Firewalls Must Rely on Behavioral Signals
Contextual firewalls analyze usage patterns, user identity, and device posture. They react to anomalies in real-time instead of static rules. This shift is essential but still rare in most enterprises.
