AI moves faster than any legacy security tool was built to handle. A large enterprise now has thousands of employees running tens of thousands of AI sessions, which add up to millions of events, tool calls, and reasoning steps every day. Agents already outnumber people, and the attack surface is larger than most security teams realize.
Today's tools weren't designed for this. Legacy security platforms give up depth to get breadth, so they see a little of everything and understand very little of it. Newer point tools protect one layer of the stack and ignore the rest. Security teams end up deploying and stitching together several tools, and still can't see the whole picture. You've always needed defense in depth. Now you need defense in depth purpose-built for AI.
Runlayer Runtime Security gives security teams the depth and breadth needed to secure employee AI use at enterprise scale. With vendor-agnostic coverage, deterministic policies, and proprietary models that detect threats in real time, you can keep the business on the golden path to AI adoption.
Cover every AI client, model, and harness
Your employees don't use one AI tool. They use hundreds, and that list changes every week. Runtime security only works if it sees every session, wherever it runs. If one client or model provider falls outside your coverage, that's where the next incident starts.
Runlayer is fully vendor agnostic and built for enterprise scale:
- Integrate with every client, model provider, and harness you use
- Layer endpoint clients, browser extensions, and inference hooks for full coverage
- Future-proof your internal AI strategy with Runlayer’s extensive integrations
With Runlayer, no AI session falls outside your defenses.
Shrink your attack surface with deterministic policies
Hardening your environment with deterministic policies is a crucial layer in your AI defense strategy. Implementing least privilege access policies and blocking the use of destructive tool calls goes a long way towards reducing your attack surface. Describing what you want to restrict in plain language is simple, for instance, “allow my Sales team to read data from GitHub, but prevent them from running write actions”. The challenge most Security teams face is figuring out how to actually enforce those policies at runtime.
To successfully implement runtime policies, you need a deterministic engine that makes it easy to translate policy descriptions into enforceable rule sets. With Runlayer, you can:
- Define and enforce granular policies across agents, users, MCPs, and individual tool calls
- Assign policies to groups and teams from your IdP, so everyone in a similar role follows the same controls
- Create policies from natural language prompts to simplify setup
With Runlayer, risky access is closed off before anyone can use it.
Detect and block risky behavior at runtime
Policies make the environment harder to attack. Some threats still show up inside approved tools, like a prompt injection hidden in a document or an agent that slowly drifts from its original task. Catching those means inspecting content and behavior while the session runs.
Runlayer's proprietary models and scanners watch every session as it runs. Out-of-the-box scanners detect and prevent AI threats, including:
- Prompt injection and invisible characters
- Credential and PII exposure
- Data exfiltration
- Intent drift and agent manipulation
- Unnecessary tool access and risky skill files
Start in alert-only mode to set a baseline for your environment, then switch to block mode to stop threats as they happen. Each scanner is configurable, for example, you can choose which types of PII Runlayer masks or blocks.
When something does trigger, you get the context you need to respond. Full session traces show exactly where things went off the rails and what Runlayer did about it. Audit logs, incident metadata, associated users, and the AI clients involved are clearly presented.
With Runlayer, threats are stopped mid-session, not discovered after the fact.
Make the safe path the golden path
Enterprise security teams shouldn't have to choose between keeping up with AI and keeping it secure. Runlayer doesn't make you choose. Runlayer Runtime Security brings vendor-agnostic coverage, deterministic policies, and proprietary runtime detection into one platform, so you can say yes to AI with confidence.
