API Security Services

Protect your APIs with strong authentication, gateway controls, and real-time anomaly detection engineered to secure sensitive data, prevent abuse, and harden every integration layer across microservices and multi-channel applications.

At Radiansys, we secure REST, GraphQL, SOAP, and Event-Driven APIs with identity-driven authentication, gateway enforcement, traffic controls, and continuous monitoring built for high-scale, distributed environments.

Strengthen API access with OAuth2, OIDC, JWT, and mTLS-based controls.

Protect endpoints using gateways, WAF policies, schema validation, and threat filtering.

Prevent abuse through rate limiting, throttling, quotas, and bot-resistant traffic management.

Optimize speed, SEO, and mobile-first performance across all devices.

How We Implement API Security

At Radiansys, API Security is treated as a complete engineering discipline. We design security layers where authentication, authorization, traffic controls, threat detection, and compliance work together to protect APIs across cloud, on-prem, and hybrid systems. Our frameworks ensure every API is authenticated, rate-controlled, monitored, and governed with an audit-ready posture.

Authentication & Authorization

We implement OAuth2, OIDC, JWT, mTLS, and API key–based authentication to establish a secure identity foundation for every API consumer. Access is governed through RBAC and ABAC models that segment permissions for users, microservices, and external partners. Token lifecycles are managed with rotation, revocation, and secure storage, ensuring that only verified and authorized entities can interact with your APIs.

01

API Gateways & Edge Security

Gateways such as Kong, Apigee, AWS API Gateway, and Azure API Management act as the enforcement layer for routing, security filtering, caching, and global traffic controls. We configure WAF policies, schema validation, and payload sanitization to block injection attempts, malformed requests, and protocol-level threats. This centralized control strengthens edge security while reducing operational complexity.

02

Traffic Management & Abuse Prevention

We implement rate limiting, throttling, quotas, spike control, and circuit breakers to defend your APIs against DDoS attacks, credential stuffing, brute-force attempts, and bot-driven traffic. These controls ensure predictable performance while preventing noisy neighbors or abusive clients from overloading backend systems. Analytics pipelines monitor consumption trends and help refine policies for internal and external consumers.

03

Monitoring, Logging & Anomaly Detection

Structured logging, distributed tracing, and real-time telemetry are enabled across all API layers to provide deep visibility into request flows. We integrate logs with SIEM platforms to detect anomalies such as unusual bursts, repeated token failures, or suspicious payload signatures. Alerts and automated responses help identify and contain threats before they escalate into data exposure or downtime.

04

Compliance & Governance

We align API ecosystems with PCI DSS, SOC2, HIPAA, ISO 27001, and GDPR requirements by standardizing authentication rules, encryption practices, and audit-ready logs. Governance frameworks cover versioning, schema validation, partner access controls, and lifecycle policies to ensure APIs evolve safely. These controls reduce risk, improve traceability, and maintain compliance across distributed architectures.

05

Use Cases

Secure Partner Integrations

Protect partner-facing APIs with OAuth2, gateway controls, and rate limiting to ensure safe access and prevent misuse across external systems.

Fraud & Abuse Prevention

Deploy anomaly detection, quotas, and WAF rules to block automated scripts, fraudulent requests, and bot-driven spikes before they impact your services.

API Modernization

Migrate legacy SOAP or XML services to secure REST or GraphQL APIs with strong authentication, improved governance, and modern gateway enforcement.

API Governance at Scale

Standardize authentication, schema validation, and access rules across large API portfolios with centralized governance and automated policy controls.

Business Value

Strong API Defense

Reduce risks from authentication flaws, data leakage, and injection attacks with layered API security controls.

Regulatory Compliance

Meet PCI DSS, SOC2, HIPAA, ISO 27001, and GDPR requirements with audit-ready logging and access control frameworks.

Lower Fraud & Abuse

Rate limiting, anomaly detection, and gateway enforcement significantly reduce malicious traffic and fraudulent API calls.

Faster, Safer Integrations

Secure APIs enable quicker partner onboarding with consistent authentication, predictable performance, and governed access.
