Secure Modern Software End-to-End with Levo’s Runtime Security Modules

Today, Levo.ai adds next generation ADR (application detection and response) modules to better assist your DevSecOps teams. Coverage for APIs is the first one to be generally available, comprising Levo’s API Detection and API Protection modules. 

Where: These modules will appear as separate tabs underneath our proactive & governance modules
When: Generally available starting now. 

How: Customers can reach out to their respective account executives to activate these modules and control access through RBAC. 

TL;DR

Application Detection and Response (ADR) secures APIs and applications in real time by detecting and blocking threats during execution.
Legacy tools fail because they miss internal API activity and business logic attacks.
Runtime ADR provides context-aware detection, accurate alerts, and continuous protection across the application lifecycle.

1. Protect Applications from code to production

Levo safeguards your software at every stage, from the first line of code to live in production. This unified approach means most vulnerabilities are found and fixed before release, and live applications stay secure without sacrificing developer velocity or security budgets.

2. Defend Applications against API business logic attacks

Legacy tools miss subtle API attacks that abuse your APIs in ways they were never intended to be used. Levo understands how each API should behave, so it blocks unauthorized actions and keeps sensitive data and user trust safe.

3. Strengthen Security Posture continuously 

Security isn’t set‑and‑forget. Levo learns from every deployment, so your defenses improve with each release. Our production security modules strengthen resilience and security by feeding this threat intelligence to shift-left modules to create custom test cases and monitoring alerts. 

4. Cut Security TCO and Security Risks

By processing data locally in customer environments rather than in our SaaS, Levo avoids the massive cloud overhead, budget overruns, privacy concerns, and latency that accompany legacy ADR. No sensitive data or traces leave customer environments, and only metadata (less than 1% of traffic) is sent to Levo’s SaaS. 

5. Cut Alert Fatigue, MTTD , and MTTR

Levo delivers high-signal, low-volume alerts that matter, enabled by kernel‑level runtime visibility. Teams spend more time defending applications against real threats and zero time triaging noise to find them. Context, clarity, and control improve all relevant metrics: mean time to detect, mean time to respond, and root-cause remediation.

Conclusion

Application Detection and Response is essential because modern attacks target API behavior, internal communication, and business logic where legacy tools have no visibility. Static testing and perimeter defenses fail to detect these runtime threats, resulting in missed attacks and alert fatigue.

Effective security requires continuous, context-aware monitoring and enforcement at runtime, where every action is validated based on identity, behavior, and data flow. This ensures accurate detection, faster response, and reduced operational noise.

Levo enables this shift by combining runtime API detection, protection, and shift-left security into a single system, giving teams full visibility and control without adding complexity or overhead.

Adopt runtime ADR to secure APIs, reduce noise, and scale application security with confidence.

FAQs

What is Application Detection and Response (ADR)?
Application Detection and Response (ADR) is a security approach that detects and blocks threats in applications during runtime. It uses real-time behavior and context to identify risks.

Why is ADR important for API security?
ADR is important because APIs are a primary attack surface. It detects threats like business logic abuse and unauthorized access that legacy tools cannot see.

What are runtime API detection and protection?
Runtime API detection identifies threats in live API traffic, and protection blocks those threats instantly. Together, they secure APIs during execution.

Why do legacy tools fail against modern API attacks?
Legacy tools fail because they rely on static analysis or perimeter monitoring. They cannot detect internal API calls, dynamic workflows, or runtime behavior.

What are API business logic attacks?
API business logic attacks exploit how APIs are designed to function. Attackers manipulate workflows or sequences to perform unauthorized actions.

How does ADR reduce alert fatigue and improve response time?
ADR reduces alert fatigue by generating only high-confidence alerts based on context. This improves detection accuracy and speeds up response and remediation.
