Proof against Evasion AttacksAttackers usually search to bypass WAF protections utilizing new protocols or evasion methods. SafeLine’s semantic engine is troublesome to bypass as a result of it understands the intent behind requests fairly than simply matching recognized patterns.
Scalable and Excessive-PerformanceUnder excessive visitors volumes, many WAFs expertise efficiency degradation.
SafeLine helps multi-node configuration synchronization, permitting organizations to simply arrange load balancing and failover mechanisms with minimal effort.
By configuring a number of SafeLine nodes, customers can distribute incoming visitors evenly throughout servers, guaranteeing optimum efficiency and stopping any single node from turning into a bottleneck.
This setup not solely improves the general responsiveness of internet functions but additionally enhances system reliability.
Within the occasion that one node experiences failure or downtime, it may well redirect visitors to wholesome nodes with out interrupting person entry.
The synchronization course of retains all nodes updated with the newest safety insurance policies and configuration modifications, sustaining constant safety throughout your complete deployment.
Implementing a resilient, high-availability atmosphere is easy with SafeLine—even for groups with out intensive infrastructure administration expertise.
Superior Bot and Automated Menace DefenseHandling malicious bots and automatic assaults has grow to be an more and more complicated and pressing problem, particularly as AI applied sciences proceed to advance and empower attackers with extra refined instruments.
