Runtime API Protection Without the Trade‑Offs

When API Protection Misfires, Availability, Revenue, and Trust Take the Hit

Overly aggressive rule sets routinely stop legitimate API calls; studies show nearly half of WAF deployments run in “log only” mode because teams are afraid to block.
Signature-based approaches don’t catch business-logic abuse or obfuscated payloads. In one comparison, a leading WAF missed 88 % of real attacks.
Old proxy models fail closed or fail open, turning the blocker into a single point of failure. Latency compounds at scale, and downtime becomes another business risk.
Inline Control Without Legacy Trade‑Offs
Precision blocking with white‑box rules:
Replace opaque, vendor‑managed rules with a transparent engine. Levo ships curated base policies and lets you author or approve your own. Every decision is explainable and tunable, driving high true‑positive rates without sacrificing user experience.

Sub‑millisecond overhead, built for resilience
Levo’s protection module is stateless and engineered for single‑digit milliseconds of latency. It scales with your traffic and avoids the fail‑open/fail‑closed scenarios that cause outages.

Local analysis and zero egress
Traffic is processed by the Levo Satellite inside your environment, so sensitive payloads never leave your network. You avoid multi‑hundred‑thousand‑dollar egress bills and data‑residency concerns while retaining rich analysis.

Block Real Threats Without Breaking Teams
Ship without second‑guessing. Transparent, precise rules mean your releases won’t be blocked by false positives.
Secure more with less. High‑fidelity, explainable enforcement eliminates triage overhead, letting lean teams focus on remediation.
Prevent incidents instead of reporting on them. Local enforcement and audit‑ready evidence reduce breaches and prevent incident response.
Stop attacks, not customers. Sub‑millisecond protection, zero data egress.

What is API Inventory?
Levo’s API Inventory is a continuously updated, behavior-aware map of all APIs across your environments. It’s not just a list, it’s a real-time foundation for enforcing security controls, meeting compliance mandates, and accelerating secure development because enterprises can't secure what they can't see.
Why is keeping an API Inventory important?
You can’t secure what you don’t know exists. Without a reliable inventory, critical APIs may remain unmonitored, unauthenticated, or misconfigured, becoming easy targets for attackers. Inventory gaps also lead to incomplete testing, failed audits, and policy enforcement blind spots.
How can API Inventory be maintained?
Traditionally, API inventories are built through manual tagging, dev surveys, or quarterly audits but these are error-prone and quickly outdated. The only sustainable way is through continuous, automated discovery that keeps pace with CI/CD and cloud sprawl.
How does Levo solve the API Inventory problem?
Levo uses a powerful eBPF-based sensor and over 12 agentless techniques to continuously discover and catalog every API internal, external, shadow, zombie, third-party across every environment. It requires no code or config changes and updates in real time as APIs are deployed or changed.
How is Levo better than other solutions available in the industry?
Most tools rely on static scanning, documentation parsing, or traffic sampling with limited visibility. Levo offers behavior-aware, context-rich, and environment-specific API discovery. It doesn’t just list APIs, it understands how they behave, what risks they pose, and who owns them.
What kinds of APIs does Levo discover?
Levo automatically detects internal, external, partner, third-party, open-source, shadow, and zombie APIs across REST, GraphQL, gRPC, and SOAP protocols. Even rarely used or low-traffic endpoints are surfaced and monitored.
How does Levo discover shadow and zombie APIs?
Levo combines code-based instrumentation with traffic analysis to uncover both unused or undocumented APIs in your codebase (shadow/zombie endpoints) and validate their runtime behavior. This dual approach ensures even rarely called or inactive endpoints are surfaced before attackers exploit them.
What makes Levo’s inventory “smart” or behavior-aware?
Each API in Levo’s inventory is enriched with metadata like authentication scheme, rate limits, status codes, version history, and sensitive data exposure. Teams can filter or group APIs based on behavior, making it easier to prioritize risk and streamline security testing.
How does Levo keep its API inventory continuously updated?
Levo detects new APIs as they’re deployed or integrated. Version history is tracked automatically, and changes are flagged in real time. This prevents drift between environments and keeps security and compliance aligned with what’s actually running.
How does Levo discover APIs without requiring code changes or developer time?
Levo captures API traffic directly at the kernel layer using eBPF sensors, completely out-of-band. This passive, pre-encryption visibility requires no code changes, no config edits, and no developer involvement. For restricted environments, Levo supports agentless, log-based, and file-based ingestion methods.
Which platforms does Levo integrate with?
Levo is platform-agnostic and supports all major environments including dev, staging, UAT, SIT, and production across hybrid, multi-cloud, and containerized infrastructures. It integrates seamlessly into CI/CD pipelines, observability platforms, and developer workflows.
How is Levo’s API inventory different from existing tools?
Levo's inventory is built from live runtime behavior, not stale snapshots or user-submitted specs. It includes rich metadata like auth schemes, rate limits, version history, and error behavior and flags risks in real time, enabling action, not just visibility.
Does Levo track APIs across different environments?
Absolutely. Levo offers environment-specific visibility, meaning you can track how APIs behave differently across dev, staging, production, and other environments providing accurate context for prioritization, testing, and risk reduction.
How does Levo help with compliance audits?
Levo provides exportable, always-updated records of API assets, auth posture, data exposure risks, and testing coverage eliminating the need for manual interviews, spreadsheets, or last-minute scrambles during compliance cycles.
Does Levo provide risk context for each API?
Yes. Each API is enriched with actionable risk signals such as exposure of sensitive data, missing authentication, or inconsistent rate limits so security and compliance teams can prioritize efforts intelligently.
Will developers need to tag or declare APIs manually?
No. Levo requires zero developer intervention to detect, tag, or declare APIs. Everything is automatically discovered and contextualized so developers stay focused on building, not inventory maintenance.
