Adaptive defense for network-layer attacks, mitigated inside your own data center based on real traffic behavior.
SYN floods, UDP floods, ICMP floods, amplification, and fragmentation attacks target the network layer. Before they ever reach the application, they can exhaust connection pools, bandwidth, processing capacity, or the network gateway.
Classic static thresholds don't produce the same outcome in every environment. Traffic that is normal for one organization may be an attack for another. A threshold that looks safe during the day may sit far too high at night; a campaign-period threshold may produce false alarms on a normal day.
TR7 L4 DDoS Protection learns your network's normal behavior and decides against that normal during an attack. Attack traffic is filtered on your TR7 ADC platform — not routed off to a third-party scrubbing cloud. Data locality, latency control, and operational ownership stay with you.
Not a static threshold — your network's actual behavior.
L4 DDoS Protection combines baseline learning, multi-vector filtering, and topology-aware thresholds to stop network-layer attacks inside your own network. Defense without sending attack traffic to a third-party scrubbing cloud.
L4 DDoS Protection combines normal-traffic learning, multi-vector attack filtering, and topology-aware decisions. Instead of a single static threshold, defense follows the organization's actual network behavior.
TR7 watches your network's normal traffic behavior and builds a baseline over time. During an attack, the decision is made against the organization's own traffic profile — not against generic assumptions.
DDoS campaigns usually arrive in more than one form. SYN floods, UDP floods, ICMP floods, amplification, and fragmentation can run together in the same campaign.
Every organization has a different network, application set, traffic source, and load cycle. The same threshold doesn't produce the same result everywhere. TR7 evaluates thresholds with service and topology context.
L4 DDoS Protection is not a separate appliance or a third-party cloud scrubbing service. It is a premium defense layer that runs on TR7 ADC. Network-layer attacks are absorbed in infrastructure you own — without redirecting traffic anywhere else.
L4 DDoS Protection delivers value in attacks that target service continuity at the network layer. The goal is not just to block attack traffic, but to keep the service up by protecting real user connections.
The attacker sends a very high number of SYN packets, trying to exhaust the connection pool. If a static threshold triggers too late, the service slows; if it triggers too aggressively, real users are also affected.
TR7 already knows the normal SYN/ACK behavior from the baseline. When the anomalous SYN wave is detected, the attack traffic is filtered before the connection pool is exhausted; real user traffic is preserved.
The attacker uses DNS reflectors to direct high-volume response traffic at the organization's uplink. From the outside, the traffic looks like DNS responses — but it consumes bandwidth.
TR7 evaluates source diversity, packet size, traffic rate, and service context together. When the amplification pattern is detected, traffic is rate-limited or filtered.
A finance or government application sees heavy daytime traffic and low nighttime traffic. An attacker may launch a lower-volume but effective attack at night. A static daytime threshold can miss this.
TR7 separates the nighttime normal with hourly and seasonal baselines. Traffic anomalous against the night profile is detected earlier and the appropriate filtering is applied.
An organization focused on its home market suddenly receives high traffic volume from unexpected countries. The attack may originate from a distributed botnet.
TR7 evaluates the expected source geographies and normal traffic distribution as part of the baseline. Geographic anomaly, packet rate, and service target are analyzed together to apply the appropriate rate-limit or filtering.
L4 DDoS Protection is licensed by the number of routing tables to be protected. It scales from single-segment deployments to multi-segment enterprise networks and to multi-tenant service-provider environments.
Every ADC license ships baseline adaptive L4 DDoS protection for a standard number of routing tables. For broader scope, the capacity tiers below take over.
For PAYG customers, L4 DDoS Protection can be delivered with L7 DDoS and L7 Reporting capabilities together as part of the PAYG Extra Pack.
L4 DDoS Protection provides a strong additional security layer for keeping critical services running, applying technical measures against network-layer attacks, and tracking attack events under auditable record.
Supports technical measures for service continuity and data security on systems that process personal data. Helps reduce the risk of service interruption.
Contributes to service-continuity, network-security, event-traceability, and DDoS-defense requirements in financial systems.
Provides additional control for DDoS protection, traffic integrity, and network-layer security in critical infrastructure and enterprise networks.
Supports protection of production environments and resilience of critical application infrastructure against attacks.
L4 DDoS Protection is available as a Premium add-on for all four TR7 bundles (Base, Geo, Secure, and Enterprise). Adaptive baseline learning, multi-vector filtering, topology-aware thresholds, SIEM streaming, and audit trail are included in the add-on scope.
Let's model your environment together in an L4 DDoS Protection demo: which routing tables will be protected, how the normal traffic baseline will be learned, which attack vectors take priority, and how the SIEM stream will be configured.
