No Blackholing Protection for ISPs

DDoS attacks have become more sophisticated, and so have the risks of blocking legitimate traffic while trying to fend them off. Blackholing stops attacks by dropping all traffic - including legitimate users, causing full service disruption, loss of business continuity, and revenue impact.

Flowsec’s solution feels different because it “feels” different. Using machine learning to accurately classify “red” malicious attack traffic from “green”, normal and legitimate flows, Flowsec stops attacks in their tracks. WITHOUT COLLATERAL DAMAGE.

Flowsec delivers a no-blackholing approach trusted by top SPs worldwide, protecting customer activity so users keep working as usual even during attacks.

Understand how Flowsec machine learning helps distinguish malicious from legitimate traffic, keeping systems up and running even during DDoS attacks.
