2025 has been one of Wallarm’s biggest years yet. In the last few months alone, we unveiled our industry-first API Revenue Protection capability, launched our next-gen Security Edge offering, were included in the 2025 Inc. 5000 list of fastest-growing private companies in America, and announced our $55M Series C funding round. This October, we’re proud to see our dedication and our customers’ confidence recognized.

Injection attacks are among the oldest tricks in the attacker playbook. And yet they persist. The problem is that the core weakness, trusting user inputs too much, keeps resurfacing in new forms. As organizations have shifted to API-driven architectures and integrated AI systems that consume unstructured input, the attack surface has expanded dramatically.

For this Cybersecurity Awareness Month, we thought it important to draw attention to some of the most common and dangerous API vulnerabilities. This week, we’re starting with Broken Object Level Authorization (BOLA). BOLA vulnerabilities top the OWASP API Top Ten. And for good reason: they’re startlingly prevalent, remarkably easy to exploit, and can have devastating consequences. So, let’s explore what they are, why they matter, and how you can mitigate them.

AJ Debole is Field CISO at Oracle, but her journey began far from the corporate boardroom. After starting out in law and government, she moved into healthcare and cyber defense, where she led teams through ransomware crises. In this spotlight, she explores the next wave of challenges – aligning security with business incentives, taming AI sprawl, and securing the APIs that connect it all.

APIs are a blessing and a curse. They’re the backbone of the modern internet. They also expose complex behaviors that are often poorly documented, stitched together across legacy and cloud systems, and updated faster than security teams can review. Three key groups typically shoulder the burden of protecting them: When these groups work in silos, gaps appear. Security becomes fragmented, reactive, and expensive to maintain. This is where Wallarm Security Edge comes in.

When we started Wallarm, we focused on the APIs that power modern apps. We built an API-first platform, used AI from day one, and secured early patents in behavior-based detection and automated policy creation. The result: real-time, inline blocking with automatic API discovery that protects production, not just dashboards. Today’s investment isn’t only fuel for innovation—it’s proof of enterprise recognition.

Throughout the past few years, APIs have become the backbone of digital infrastructure. They enable software-to-software communication, improve integration and interoperability, support modular architecture, and more. But as API use has exploded, so has API traffic volume and complexity, making them increasingly difficult to secure. And the rise of AI agents and automation have complicated matters further. The result? APIs have become a favourite attack vector for cybercriminals.

APIs are now the beating heart of digital infrastructure. But as they have risen in importance, they’ve also become prime targets for attackers. Complex, often poorly understood API behaviors present rich opportunities for exploitation, and too often, security teams are left scrambling to protect critical infrastructure with outdated tools or cumbersome deployments. Wallarm’s Security Edge is the answer to this problem.

API security has never been more crucial. Vulnerabilities are growing in volume and severity. AI integrations are a burgeoning attack vector. Increasing GraphQL adoption presents hidden dangers. To protect your organization, you must secure your APIs. Keep reading for our key takeaways from the Wallarm Q2 2025 API ThreatStats report – and find out what you need to do to protect yourself.

Unrestricted Resource Consumption (API4:2023) is the only threat category in the OWASP API Security Top 10 explicitly dedicated to Denial of Service (DoS) and resource abuse. But despite being just one category, attackers can exploit it in many different ways; from large file uploads and expensive GraphQL queries to abuse of metered third-party services like SMS gateways or AI/LLM APIs.
