APIs Built for Performance and Protection
Secure API Development Services
We design, build and secure REST and GraphQL APIs that connect your applications and services reliably. Every API we build includes proper authentication, rate limiting and input validation from day one, so it performs well and holds up under real-world traffic and attempts to abuse it.
- Certified Experts
- OSCP, CEH, CRTP & industry-certified testers.
- Real-World Approach
- Manual testing with real-world attack techniques.
- Actionable Reporting
- Detailed findings with clear risk ratings and remediation.
- Confidential & Secure
- Strict NDA, data protection & privacy practices.
// API Security by Design
The Connective Tissue of Your Applications, Built Right
APIs are often the most exposed part of an application, connecting your systems to the outside world. We build APIs with strong authentication, strict input validation and clear documentation, so your integrations stay fast, reliable and hard to abuse.
Every API is designed and tested against the OWASP API Security Top 10, with the personal data flowing through it handled the way UK GDPR expects.
- Strong Authentication and Authorisation on Every Endpoint
- Protection against Injection, Abuse and Data Exposure
- Clear, Versioned Documentation for Developers
- Scalable Design Ready for Growth
// Coverage
What Our API Development Service Includes
REST and GraphQL Design
API design and development in whichever style suits your product.
Authentication and Access Control
OAuth 2.0, JWT and role-based access implemented properly.
Rate Limiting and Abuse Prevention
Throttling and monitoring so a single endpoint cannot be scraped.
Third-Party Integration
Connections and data synchronisation with the services you depend on.
Documentation and Versioning
Clear, versioned docs your developers and partners can actually use.
Ongoing Monitoring and Support
Continued oversight once the API is carrying live traffic.
// Methodology
How We Build Your API
- 01
Design and Threat Modelling
We map endpoints and abuse cases before development begins.
- 02
Authentication Build
Authentication, authorisation and rate limiting built in from the start.
- 03
Development
Input validation and secure defaults applied across every endpoint.
- 04
Security Testing
Testing against the OWASP API Security Top 10 before release.
- 05
Documentation and Handover
Versioned documentation delivered alongside the working API.
// Ready when you are
Put your secure api development services to the test.
// Impact
Why API Security Matters
Weak Auth Causes Breaches
APIs are a leading cause of data breaches when authentication or rate limiting is weak.
// Our Development Approach
- API design and threat modelling before development
- Authentication, rate limiting and input validation built in
- Testing against OWASP API Security Top 10 risks
What you get
// Technologies We Use
// Why Pluto Cyber Security
APIs Tested against Real-World Abuse
We build and test APIs against the same techniques attackers use to find weak endpoints, so vulnerabilities get caught before your API goes live, not after.
OWASP API Top 10 Aligned
Built and tested against the leading API security risks.
Strong Authentication
OAuth 2.0, JWT and role-based access control done properly.
Clear Documentation
Every API ships with documentation your developers can actually use.
Built to Scale
Designed for growing traffic and future integrations.
We build both, and recommend the right approach based on your application's needs.
