Blackholing has long been the default response to large-scale DDoS attacks.
It works - by dropping all traffic to the target.
Sure, the attack stops.
But so does your service. Your traffic. Your business.
At Flowsec, we take a more precise approach.
Using the ISP resources and real-time AI traffic classification, we distinguish between malicious traffic (red) and legitimate traffic (green) - Blocking only what’s harmful.
✓ Service stays online
✓ Customers stay connected
✓ Your team stays in control
In addition, our multi-tenant SaaS platform protects ISP networks with zero service disruption, even under massive attacks.
Combined with global signature sharing, we ensure that mitigation starts early, scales instantly, and always preserves user access.
Not all traffic is bad. We help the ISP tell the difference.
