Adaptive defense that understands application-layer attacks by behavior and answers with the right action.
Application-layer attacks rarely look like obvious attacks. HTTP floods, Slowloris, low-and-slow, credential stuffing, and targeted API attacks can behave like valid HTTP requests. The traffic is protocol-compliant — but it drains the application's resources, hammers the login screen, chokes API endpoints, or slows the real user experience.
TR7 L7 DDoS Protection doesn't just watch a requests-per-second threshold. For every vService, it observes traffic behavior: connection rate, request rate, path density, error rate, session behavior, IP reputation, bot score, and application response are evaluated together.
Not every high-volume burst is an attack, and not every low-rate stream is safe. TR7 analyzes the behavior; based on the attack pattern, it applies the right action — deny, rate-limit, redirect, controlled content, or local CAPTCHA.
Watch the behavior, not just the speed.
L7 DDoS Protection separates application-layer attacks more accurately using per-service traffic profiles, combined conditions, and adaptive actions. The goal is not just to stop the attack, but to keep the application running while protecting the real user.
L7 DDoS protection capabilities
L7 DDoS Protection combines behavioral analysis, per-service thresholds, and adaptive actions. That approach catches attacks that damage the application while looking protocol-compliant — more accurately than a single static threshold can.
The attack decision is not made on a single metric. TR7 evaluates several signals at once to understand whether traffic is normal, suspicious, or an attack.
Every application has different normal traffic. A login page, an API endpoint, a payment screen, and a static content service can't be protected by the same threshold. TR7 builds a separate traffic profile for every vService.
Not every attack gets the same answer. An obvious attack can be blocked; suspicious traffic can be slowed; a client thought to be a bot can be sent to CAPTCHA. The goal is to stop the attack without putting unnecessary friction in front of real users.
L7 DDoS Protection is not a separate appliance, separate service, or separate cloud layer. It is a premium protection layer that runs on TR7 WAAP. Application security, bot management, API protection, and L7 DDoS defense unify under the same policy chain.
L7 DDoS Protection delivers value in application-layer attacks that are hard to separate with classic rate limits or static WAF rules.
The attacker opens many connections and trickles data into each, draining server resources. Because requests-per-second stays low, a classic rate threshold catches the attack late.
TR7 evaluates abnormal session length, low request/response ratio, and growing active-connection behavior together. The attack traffic is filtered or rate-limited; the application's connection pool is preserved.
The attacker distributes stolen username/password pairs to the login screen from a wide IP pool. Because each IP stays at a low rate, the attack is hard to separate with rate-limit alone.
TR7 evaluates login-path density, rising 4xx errors, IP reputation, bot score, and distributed-source behavior together. Suspicious traffic is sent to CAPTCHA or rate-limit; an obvious attack is blocked.
Automation or an AI-assisted bot sends API requests at human-like rates. A single IP or a single speed signal may not clearly indicate the attack.
TR7 analyzes bot score, behavioral fingerprint, path density, and API usage pattern together. Suspicious clients can be moved into rate-limit, CAPTCHA, or block.
Environments like e-commerce, ticketing, or application portals see traffic climb very quickly. Static thresholds can either block real users or fail to separate the attack.
TR7 evaluates expected peak periods more accurately with per-service baselines. Real user traffic is preserved while bot, scraping, or attack traffic is separated.
L7 DDoS Protection is licensed by the number of vServices to be protected. It scales from small deployments to multi-application enterprise environments and service-provider scenarios.
Every ADC and WAAP license ships baseline adaptive L7 DDoS protection for a standard number of vServices. For broader scope, the capacity tiers below take over.
For PAYG customers, L7 DDoS Protection can be delivered with L4 DDoS and L7 Reporting capabilities together as part of the PAYG Extra Pack.
L7 DDoS Protection provides a strong additional security layer for service continuity, account security, blocking automated attacks, and auditable incident records on sensitive web applications.
Supports technical measures for service continuity and data security on systems that process personal data. Protects against account takeover and automated attack waves.
Provides defense against application-layer attacks and event traceability for online banking, customer portals, and financial applications.
Adds a behavioral protection layer against automated attempts, bots, and abuse aimed at financial transaction systems.
Provides additional defense against automated attack waves, bot traffic, and application-layer abuse on systems that access the cardholder data environment.
L7 DDoS Protection is available as a Premium add-on for all four TR7 bundles (Base, Geo, Secure, and Enterprise). Behavioral analysis, per-service baselines, combined conditions, adaptive actions, rate-limit, and local CAPTCHA are included in the add-on scope.
Let's walk through an L7 DDoS Protection demo against your own scenario: which vServices will be protected, which traffic behavior counts as normal, which actions will be applied, and how the integration with WAAP policies will work.
