Top API security companies.

Every single day, billions of API calls happen across the internet. Behind your favorite applications, APIs work quietly to move data and connect systems. But with the growing use of APIs, API attacks didn’t just increase – they exploded.

Take the Optus breach in September 2022, in which attackers exploited an unprotected API endpoint and accessed the personal data of up to 9.8 million customers, leading to a $10 million fine. T-Mobile faced a critical API vulnerability in January 2023, exposing data from 37 million customers.

The harsh reality is that traditional security tools built for websites and networks don’t cut it anymore. Firewalls can’t catch API-specific attacks. Regular security scans miss API vulnerabilities. Companies often learned this the hard way after losing millions of dollars and customer trust.

This blog post will teach us about the API security companies leading the API security landscape. We’ll look beyond marketing claims and dive deep into their actual capabilities. So, let’s dig in.

What are API Security Tools?

API security tools are specialized software platforms that protect APIs throughout their lifecycle, i.e., from development to deployment. These tools scan API endpoints, monitor traffic patterns, detect unusual behaviors, and block malicious requests before they can cause damage. 

Most tools come with dashboards that show real-time API activity, alert teams about potential threats, and provide detailed reports about API usage and security status.

Modern API security companies help development teams find and fix security issues early in development, track sensitive data flowing through APIs, and stay compliant with security regulations like GDPR, HIPAA, and PCI DSS.

How to Choose an API Security Company?

Before learning about top API security companies, let’s look at some common factors to keep in mind before choosing a vendor.

Security Features and Protection Depth

An API security solution must offer comprehensive protection against modern attack patterns like injection attacks, credential stuffing, and data exfiltration attempts. The tool should provide real-time threat detection, automatic API discovery, and baseline behavioral analysis of API traffic patterns.

Market Experience and Evolution

Market presence and proven experience play a crucial role in provider selection. Companies with an established track record have typically handled diverse security challenges across different industries. This experience translates into better threat detection models and more refined security rules.

Customer Support and Community

Customer feedback and support infrastructure directly impact the success of API security implementations. The best API security providers maintain strong customer support teams that understand security and development concerns. Their response times to critical security alerts should be minimal, and they should offer clear documentation and implementation guides.

Compliance and Certification Capabilities

Modern businesses must adhere to various security standards like SOC 2, ISO 27001, PCI DSS, and GDPR (based on the industry they are operating in). The chosen API security solution should help organizations meet these compliance requirements through built-in controls, audit logs, and compliance reporting features. 

The API security companies should also maintain their security certifications, demonstrating their commitment to security best practices. Their documentation should clearly outline how their tools help achieve and sustain different compliance standards.

FAQs

What are APIs in security?

In security, APIs (Application Programming Interfaces) facilitate communication between different security systems and tools. They enable automated data sharing, threat intelligence exchange, and coordinated responses to security incidents. This interoperability improves overall security posture by streamlining processes and enhancing threat detection capabilities.

What is API security risk?

API security risks arise from vulnerabilities that expose sensitive data or functionality. Common risks include broken authentication, injection flaws (exploiting input validation gaps), excessive data exposure, and lack of rate limiting. These can lead to data breaches, service disruption, or unauthorized access.

How do I secure my API?

Securing your API requires a multi-layered approach. Choose robust authentication and authorization mechanisms like OAuth 2.0. Implement input validation and output encoding to prevent injection attacks. Utilize API gateways for traffic management and threat protection. Select security tools and partners with proven expertise in API security for comprehensive protection.
