Why API Security Matters More Than You Think

Why API Security Matters More Than You Think

What are APIs?

APIs are the glue that holds the modern world together. They allow different applications and services to communicate with each other, and they power everything from e-commerce to social media. However, with this ease of connectivity comes new security challenges. If an attacker can exploit an API vulnerability, they can gain access to sensitive data, disrupt critical services, or even take control of systems.

In recent years, there has been a growing number of API attacks. There were over 100,000 API attacks reported in 2021 alone, a 600% increase from the previous year. And this trend is only expected to continue. Being the leading open source API Security platform, we've seen just how vulnerable a lot of APIs are.

Why are APIs *so* vulnerable to attack?

A few reasons make them particularly vulnerable to attacks. First, APIs are often complex and difficult to secure. Organizations often have hundreds, thousands, or even tens of thousands of API endpoints, and each API endpoint can be a potential target for attack. Second, APIs are often used to access sensitive data, such as customer data, financial data, and intellectual property. This makes them a valuable target for attackers. Third, APIs are often used in public-facing applications, which makes them more accessible to attackers.

The Risk of Insecure APIs

The risk of having insecure APIs is very significant - if an attacker can exploit an API vulnerability, they can gain access to sensitive data, disrupt critical services, or even take control of systems. For startups and small businesses, these security breaches can be catastrophic, leading to loss of trust and revenue. This can lead to financial losses, reputational damage, and even legal liability. For larger companies, the consequences are bigger yet.

What You Can Do To Secure Your APIs

There are a number of things that organizations can do to secure their APIs. Here's a few:

  • Implement strong authentication: This means using strong passwords, two-factor authentication, and other methods to verify the identity of users.
  • Use API gateways: API gateways can help to protect APIs from attack by providing a layer of security between the API and the outside world.
  • Secure the API endpoints: Each API endpoint should be secured with appropriate access controls.
  • Monitor the APIs: Businesses should monitor their APIs for suspicious activity and respond to incidents quickly.

In addition to these steps, businesses can also take advantage of security solutions that are specifically designed to protect APIs (like Metlo). These solutions can help to identify and mitigate security risks, and they can also help to automate security tasks.


API security is a complex and challenging problem. However, it is an essential part of protecting businesses and consumers from the risks of cybercrime. Inadequate API security can lead to data breaches and other security threats that can be catastrophic for startups and small businesses. However, by implementing strong API security measures, businesses can protect themselves and build trust with their customers.
