APIs power most modern applications, but securing them is still harder than it should be. APIs change frequently, span internal and third-party services, and expose business logic that static security tools often miss. For many teams, that leads to noisy alerts and limited confidence about what actually matters in production.
This is the gap
Radware is targeting with its new API Security Service. The platform brings API discovery, posture management, business logic protection, and runtime defense together, all based on live production traffic.
From theoretical alerts to real risk
Many API security tools flag potential issues based on specs or scans, but that does not show which risks are active. Radware’s approach starts at runtime.
Uri Dorot, Senior Product Manager for Application Protection Solutions at Radware told MSSP Alert, “Our new API solution is built on runtime analysis of actual production traffic, not just theoretical alerts. On day one, it gives security teams immediate insights into API security risks, based on live user interactions - including data leakage, misconfigurations, and weak authentication/authorization controls.”
Instead of generic findings, Dorot said teams see “prioritized, context-rich risks that are directly observable in their environment,” which helps cut alert fatigue and speed up response. Ongoing behavioral analysis also highlights emerging threats and posture drift as APIs evolve.
What this replaces for security teams
Many vendors now claim to cover discovery, posture, and runtime protection. Radware’s differentiation is how much manual work it removes and how closely protection is tied to live traffic.
“Unlike tools that rely on pre-deployment scans or static analysis, Radware takes what we call a runtime-first approach, continuously monitoring live API traffic and providing a single source of truth for both developer and security teams,” Dorot said.
He added that the platform automatically detects and blocks business logic attacks without manual policy tuning, and combines WAF, bot management, API security, LLM firewall, and DDoS protection in a single portal. For organizations already using WAFs or API gateways, “Radware's solution replaces manual API discovery, risk assessment, and policy tuning,” while extending protection to shadow APIs and complex business logic abuse.
How fast teams see value at scale
Large enterprises often worry that API security takes months to deploy before it becomes useful. Radware is positioning its service to move faster, even in complex environments.
“Organizations can go live in weeks, not months, and start blocking real attacks soon after deployment, even in environments with thousands of APIs and integrations,” Dorot said.
He pointed to Radware’s SecurePath architecture, which supports out-of-path deployment with no routing changes or SSL certificate sharing. SecurePath allows consistent protection across cloud, on-prem, and hybrid environments while reducing operational overhead and providing centralized visibility.
What this means for MSSPs
API security can be especially difficult for MSSPs managing multiple customers. Tools built for single environments do not scale well across tenants.
“Radware SecureApp is a fully managed, multi-tenant cloud service, allowing MSSPs to onboard tenants quickly, with branded customer dashboards and centralized threat and incident visibility,” Dorot said. Because much of the analysis and tuning is automated, he noted there is less need for deep in-house expertise.
That model allows MSSPs to add per-application API security services, scale faster, and offer higher-value protections without building or maintaining backend infrastructure.
APIs are dynamic and business-critical, and attackers operate at runtime. Static visibility is no longer enough. Radware’s API Security Service reflects a broader shift toward grounding API security decisions in live traffic, real behavior, and observable risk. For security teams, the practical impact is clearer priorities, faster response, and less manual work as API environments continue to grow.
