From WAF to LLM Guard: Why Radware's Unified AI Security Portfolio Is an MSSP Game-Changer
- Radware has merged an AI Agent security monitor with a dedicated LLM Firewall into a single portfolio, giving MSSPs a unified control plane for AI-native threat vectors.
- The two tools address fundamentally different attack surfaces: unauthorized agent actions versus prompt injection (manipulating an AI's instructions to extract data or trigger unintended commands) targeting LLM endpoints.
- Industry analyst composites suggest fewer than 20% of enterprises currently have dedicated AI runtime security controls deployed — a gap that Radware's combined offering directly targets.
- Organizations running AI agents or customer-facing LLM applications should treat these controls as foundational, not optional, given the expanding blast radius of AI-driven attacks across enterprise workflow stacks.
What Happened
What if the most dangerous gap in your organization's security posture isn't in your firewall rules or endpoint agents — it's in the AI applications your development teams deployed six months ago without a security review?
According to MSSP Alert, as reported through Google News, Radware has officially combined its AI Agent security capabilities with a dedicated LLM Firewall (a purpose-built filter for large language model inputs and outputs) into a consolidated portfolio targeting enterprises and Managed Security Service Providers. The move signals a deliberate pivot in how the network security vendor approaches threat intelligence: not as a single-product discipline, but as a layered practice requiring purpose-built controls for AI's unique attack surface.
The combined offering positions itself as a full-spectrum answer for organizations running agentic AI workflows — autonomous AI systems that take actions on behalf of users or other systems — alongside customer-facing or internal large language model deployments. Rather than assembling point solutions from multiple vendors, the portfolio gives MSSPs a single-vendor control plane to monitor, filter, and block threats across both AI tiers.
The timing reflects a market reality security teams have been quietly wrestling with: traditional web application firewalls (WAFs) were engineered for structured HTTP requests, not for the fluid, natural-language inputs and autonomous decision chains that define modern AI applications. Prompt injection attacks, data exfiltration through model outputs, and rogue AI agent actions represent threat categories that simply did not exist in the pre-LLM era — and most enterprise security stacks were not designed to catch them. Solid cybersecurity best practices now demand AI-specific controls alongside conventional network defenses.
Why It Matters for Your Organization's Security
The blast radius of a compromised AI agent is qualitatively different from a compromised web endpoint — and that asymmetry is exactly why generic security controls fall short.
A traditional server breach gives a threat actor access to data stored on that system. A compromised AI agent — one with permissions to read email, execute code, query databases, and send messages on behalf of a user — can move laterally across an organization's entire workflow stack within minutes. That threat profile requires dedicated threat intelligence tooling, not just an extension of existing WAF policies.
Radware's dual-tool approach maps directly onto the two most critical AI security failure modes identified by the OWASP LLM Top 10 (the industry's canonical list of large language model vulnerabilities):
- Prompt Injection (OWASP LLM01): A threat actor crafts inputs designed to override an LLM's system-level instructions, redirecting the model to leak sensitive data, bypass access controls, or execute unauthorized actions. The LLM Firewall component operates as a semantic inspection layer — analyzing both inputs and outputs for policy violations before they reach or leave the model. Strong data protection posture requires this control at every externally accessible LLM endpoint.
- Excessive Agent Permissions and Unsafe Actions (OWASP LLM08): Autonomous AI agents operating with overly broad permissions represent a persistent threat to enterprise data protection. Without runtime behavioral monitoring, an agent can be manipulated or misconfigured to perform actions far outside its intended scope — including accessing regulated data stores, triggering financial transactions, or contacting external systems. The AI Agent monitor enforces behavioral boundaries and flags anomalous action chains before they escalate.

The chart tells the core market story directly: most enterprise security programs have built solid foundational stacks. Traditional WAFs, EDR (Endpoint Detection and Response) tools, and SIEM (Security Information and Event Management) platforms are broadly deployed. AI-native security controls remain an afterthought for the overwhelming majority of organizations. Enforcing threat intelligence that can reason about semantic attacks — not just packet patterns — requires an entirely new category of tooling.
For MSSPs, the consolidated portfolio removes a significant operational friction point. Managing separate vendor relationships for AI agent monitoring and LLM firewall enforcement adds complexity to incident response workflows and creates coverage gaps during vendor-to-vendor handoffs. A unified telemetry stream covering both the agent action layer and the LLM input/output layer means analysts can correlate events across AI tiers without manually stitching logs from disparate systems. That integration efficiency translates directly into faster mean time to detect and contain for AI-specific incidents.
Industry-wide, cybersecurity best practices are evolving to recognize that AI applications require their own security lifecycle — secure design, runtime controls, and continuous behavioral monitoring against evolving prompt-based attack patterns. Organizations treating their LLM deployments identically to standard web applications are very likely operating with material blind spots in their data protection posture.

The AI Angle
Radware's combined portfolio lands within a broader industry inflection that the Agentic AI Scorecard recently documented: autonomous AI workflows deliver measurable operational gains, but their attack surface is fundamentally harder to instrument than conventional software. That analysis highlighted how AI agents can implode precisely when they operate outside monitored boundaries — which is exactly the threat vector Radware's agent monitoring component targets.
The LLM Firewall represents an emerging product category that operates on principles distinct from conventional security tooling. Rather than inspecting headers, payloads, or behavioral signatures, it performs semantic analysis — evaluating whether an input or output violates defined policies at the meaning level. This demands purpose-built threat intelligence models trained on adversarial prompt patterns, jailbreak techniques (methods attackers use to bypass an AI's content restrictions), and data exfiltration vectors specific to language model architectures.
Pairing this with an AI Agent monitor creates a defense-in-depth stack: the firewall governs what the model receives and outputs, while the agent monitor tracks what the model then does in the broader system. Security awareness among development teams remains critically low regarding these specific controls — which is precisely why MSSP packaging accelerates adoption. Vendors who pre-integrate both layers give managed security providers a credible, deployable AI security answer without requiring deep in-house AI expertise from every client organization.
What Should You Do? 3 Action Steps
Before evaluating any vendor solution, security teams should catalog every internal and customer-facing AI application — including LLM-powered chatbots, agent frameworks, and API wrappers around foundation models. For each deployment, document whether runtime controls exist for input validation, output filtering, and behavioral monitoring. Applying cybersecurity best practices to AI starts with visibility: you cannot protect what you have not inventoried. This audit will also surface which gaps Radware-style tooling would close versus what requires process and data protection policy changes at the application design level.
Most incident response playbooks were written before LLMs and AI agents reached production. Run a structured tabletop exercise — a facilitated simulation where your security and engineering teams walk through a hypothetical attack without using live systems — specifically around a prompt injection scenario or an AI agent executing unauthorized data access. Map exactly where your current stack generates alerts, where coverage drops, and what manual steps analysts would need to take. This exercise consistently surfaces telemetry gaps that purpose-built AI security tools address, while building security awareness across development teams who own AI systems but may not identify as security stakeholders.
When assessing Radware or any competing AI security vendor, require explicit mapping against the OWASP LLM Top 10. Ask specifically: does this tool detect and block prompt injection (LLM01)? Does it prevent sensitive data disclosure through model outputs (LLM02, directly relevant to your data protection obligations under frameworks like GDPR and HIPAA)? Does it support agent action logging for detecting excessive permissions (LLM08)? Vendors who provide direct OWASP coverage mapping give procurement teams a structured framework for evaluating threat intelligence depth, rather than relying solely on marketing claims. Ship this evaluation checklist today — it applies to every AI security conversation your organization will have going forward.
Frequently Asked Questions
How does an LLM firewall differ from a traditional web application firewall for protecting AI systems?
A traditional WAF inspects HTTP traffic for known attack signatures — SQL injection strings, malformed headers, abnormal request rates. An LLM firewall operates at the semantic level, analyzing the meaning of natural language inputs and model outputs for policy violations, prompt injection attempts, and data protection breaches. Because adversarial instructions can be embedded in ordinary-looking text that bypasses packet-level inspection entirely, the two tools address fundamentally different threat surfaces. Organizations deploying LLMs for customer-facing or internal use should consider both as complementary — the WAF protects the network transport layer while the LLM firewall protects the model interaction layer. Neither replaces the other.
What is prompt injection and how should businesses protect against it in enterprise LLM deployments?
Prompt injection is an attack technique where a threat actor embeds malicious instructions inside user-supplied text to override an LLM's system-level directives — conceptually similar to SQL injection but targeting natural language rather than database queries. The manipulated model may then leak confidential data, bypass access controls, or perform actions on the attacker's behalf. Defending against it requires layers: an LLM firewall at the input and output boundary, strict system-prompt isolation in application architecture, output validation to catch anomalous responses, and least-privilege design ensuring the model can only access what it genuinely needs. Cybersecurity best practices also require regular red-teaming (adversarial testing of AI systems) to identify novel injection vectors before attackers do. Security awareness training for developers who write system prompts is an equally critical compensating control.
Why are MSSPs the primary distribution channel for Radware's combined AI security portfolio?
Most small and mid-market enterprises lack the in-house expertise to configure, tune, and monitor purpose-built AI security controls. MSSPs already own network and endpoint security relationships with these clients — extending that relationship to cover AI application threat intelligence is a natural commercial expansion. From the MSSP's operational perspective, a single-vendor portfolio covering both AI agent monitoring and LLM firewall enforcement eliminates the complexity of managing separate vendor SLAs, disparate log formats, and disjointed incident response workflows. Radware's packaging strategy shortens MSSP time-to-deployment by removing the custom integration work that slowed earlier AI security adoption cycles.
How do AI agents create new data protection risks compared to traditional software applications?
Traditional software performs deterministic, explicitly programmed operations. AI agents introduce probabilistic decision-making with dynamic tool use — given the same starting state, they may take different action sequences on different runs. An agent with permissions spanning email, file storage, and external APIs can execute novel action chains that developers never explicitly anticipated, making comprehensive pre-deployment data protection risk assessment difficult. If an agent is manipulated through prompt injection or misconfigured with excessive access rights, it can traverse multiple data stores and external systems within a single automated workflow. Behavioral monitoring — tracking what the agent does in real time against a defined policy — is therefore an essential compensating control that cannot be substituted by access controls alone.
What incident response steps should a security team take after detecting a prompt injection attack on a production LLM?
Effective incident response for a confirmed prompt injection event should follow this sequence: (1) Isolate the affected LLM endpoint by taking it offline or routing all traffic through a stricter inspection proxy until scope is understood. (2) Preserve full input and output logs tied to the detected injection — these are forensic evidence and establish the attack timeline. (3) Audit AI agent action logs for any downstream actions the model may have executed as a consequence of injected instructions, focusing on data access, external API calls, and message sends. (4) Engage your data protection compliance team if any sensitive, regulated, or personally identifiable records may have appeared in model outputs. (5) Update LLM firewall rules to block the identified injection pattern and its known variants. Treat this as a standard application-layer breach: contain, collect evidence, assess blast radius, remediate the root cause, and report per your regulatory obligations. Do not resume production traffic until behavioral testing confirms the injection vector is closed.
