Shining a Light on API Security: What We Learned from Our Webinar with Thales

APIs are now fundamental to how modern organisations operate. They connect systems, enable innovation, and power digital services but they’re also becoming one of the most overlooked areas of security risk.

In our recent webinar with Thales, we brought together industry experts to explore the reality of API security today, the challenges organisations are facing, and the practical steps needed to improve visibility and control.

A clear message emerged throughout the session:

API security isn’t just a technical issue - it’s a visibility and understanding challenge.

APIs Are Everywhere, But Not Always Visible

One of the most consistent themes from the discussion was visibility.

Many organisations simply don’t have a complete picture of their API landscape. Over time, APIs are created across development cycles, cloud platforms, integrations and third-party services, often without central oversight.

This raises some important questions:

• Do you know how many APIs your organisation has?
• Can you see how they’re being used?
• Do you understand what data they expose?

For many, the honest answer is “not entirely.”

Without that visibility, security teams are left reacting to issues rather than proactively managing risk.

Why APIs Are an Attractive Target

APIs behave differently from traditional infrastructure and attackers know it.

During the session, we explored how APIs sit outside conventional security controls, how they change frequently as applications evolve and are often poorly documented or unmanaged.

This creates an environment where risk can remain hidden in plain sight.

Rather than targeting hardened infrastructure, attackers are increasingly using APIs as a route into systems - accessing sensitive data without triggering traditional security alerts.

The Problem with a Tool-First Approach

Another key takeaway was that API security can’t be solved by technology alone.

While tools play an important role, the session emphasised that organisations often jump straight to solutions without first understanding their environment.

Effective API security starts with three fundamentals:

1. Understanding what APIs exist
2. Knowing how they’re used
3. Identifying where the real risks sit

Only then can meaningful controls be applied - whether around access, monitoring or data protection.

Protecting What Matters Most: The Data

A particularly important part of the conversation focused on data.

APIs are not just endpoints, they are conduits for sensitive information. That means even if an API is accessed, the real impact depends on how well the underlying data is protected.

This is where approaches such as encryption, tokenisation and strong key management become critical.

By protecting the data itself, organisations can significantly reduce risk - even in the event of an API being exposed.

From Insight to Action

The webinar wasn’t about perfect solutions - it was about practical next steps.

For most organisations, the starting point is simple: Take a step back and properly assess your API landscape.

Not just what’s documented, but what actually exists.

From there, you can begin to:

• Improve visibility
• Apply consistent controls
• Reduce exposure
• Build a more resilient security posture

Final Thoughts

APIs are only going to become more central to how organisations operate.

The challenge isn’t their growth, it’s actually the lack of visibility and control around them.

If you can’t see your APIs, you can’t secure them.
