Runtime Protection & WAF

Most guides on mobile app security best practices read like a pile of disconnected tips: encrypt data, use 2FA, keep dependencies updated. The problem with flat lists is that they tell you what to do but not where each control belongs. Is certificate pinning something you configure at build time, enforce at runtime, or handle […]

Node.js security has two layers, and most teams only build one of them. The first is pre-deployment hardening: input validation, dependency scanning, security headers, secrets management. The second is runtime defense: protecting the application while it runs in production, intercepting attacks as they happen inside the code. Most articles cover the first layer in depth. […]

Most teams deploy a WAF, enable the default ruleset, and consider the job done. Then three months later they’re drowning in false positives, blocking legitimate users, or discovering that a real attack slipped through because the attacker used URL encoding the rule didn’t account for. Web application firewall rules are not a set-and-forget configuration. They […]

Every guide on RASP vs WAF ends with the same conclusion: “use both together.” That advice is technically sound but practically incomplete. It assumes you only have two options. A third architecture exists that the industry has not cleanly categorized yet: the In-App WAF. It operates inside the application like RASP, intercepts at precise execution […]

Most organizations running web applications have two security layers in place: a network firewall at the perimeter, and a web application firewall in front of the app. On paper, the coverage looks solid. The network firewall handles unauthorized traffic at the network level. The WAF filters malicious HTTP requests before they reach the server. And […]

You’ve enforced HTTPS. You’re using parameterized queries everywhere. Input validation is tight. Your dependency scanner runs on every PR. By any reasonable checklist, your .NET application is secure. Then someone decompiles your assembly with ILSpy, finds a hardcoded token you missed, and leverages it against your production API. Or an attacker sends a carefully crafted […]

Every application that integrates an LLM is now a potential attack surface. Unlike SQL injection or XSS, prompt injection can’t be fixed with a parameterized query or an output encoder. The LLM processes system instructions and user input as a single undifferentiated text stream. There is no type boundary, no syntax separator, no technical wall […]

AI is reshaping both sides of cybersecurity. Attackers use it to scan for vulnerabilities in minutes, craft targeted phishing campaigns at scale, and execute autonomous intrusions that move faster than any human analyst can track. Defenders use it to process millions of signals per second, detect behavioral anomalies, and respond to threats before they escalate […]

The global web application firewall market is worth over $6 billion and growing. Security teams spend months evaluating vendors, comparing rule sets, tuning anomaly scores, and finally deploying a WAF in front of their applications. Then a penetration tester shows up, spends forty minutes with a proxy tool, and walks through it. This is not […]

Most DDoS protection guides stop at the network layer. Block the traffic before it reaches your servers, absorb the volumetric flood with a CDN, done. But Layer 7 DDoS attacks don’t work that way. They look like normal web traffic because, technically, they are. The requests complete the TCP handshake, follow HTTP correctly, and often […]

Containers changed how we ship software. The deployment model is cleaner, environments are consistent, and scaling became a solved problem for most teams. But containers didn’t change one thing: the applications inside them still have vulnerabilities, and attackers still try to exploit them. Most Docker security guides focus on hardening the container environment: running as […]

Bad bots account for 37% of all internet traffic, according to the Thales 2025 Bad Bot Report. Businesses worldwide lose an estimated $186 billion annually to bot-driven fraud, scraping, and automated attacks. Those numbers have been climbing every year, and the trajectory isn’t changing. The harder problem is that bot detection has never been more […]

Most application security content reads like a glossary. You get a name, a category, maybe an OWASP reference, and a paragraph explaining what the vulnerability is. That information is necessary but not sufficient. Knowing that SQL injection exists and understanding how an attacker actually exploits a search endpoint in production are two different things. This […]

Most application security tools work from the outside. Firewalls inspect traffic at the network edge. Static analyzers scan source code before deployment. Vulnerability scanners probe applications from the perspective of an attacker. All of these approaches share a blind spot: none of them can see what actually happens inside your application when it processes a […]

Every year, web application attacks account for roughly one in four confirmed data breaches. The Synopsys Open Source Security and Risk Analysis report found that 84% of audited codebases contain at least one known security vulnerability. These are not theoretical risks. They are the gaps attackers scan for every day, and the reason application security […]

According to the 2025 Verizon Data Breach Investigations Report, 42% of confirmed breaches involved the exploitation of web applications. Web application firewall best practices are supposed to prevent exactly this. But a WAF that’s deployed with default rules and never tuned is a checkbox, not a control. The gap between “we have a WAF” and […]

Jailbreak and root detection is one of those topics that every mobile developer encounters eventually, but few truly understand in depth. You build your app, implement authentication, encrypt your data, and then someone installs it on a jailbroken iPhone or rooted Android device where none of those protections work as intended. The problem is straightforward: […]

Static analysis tools scan your code before deployment. Vulnerability scanners check your dependencies against CVE databases. Perimeter firewalls inspect incoming HTTP traffic. All of these are valuable, and all of them share the same blind spot: none of them can tell you what is actually happening inside your application right now. Runtime threat detection fills […]

Application security testing is not a single tool problem. SAST scans your source code during development. DAST attacks your running application from the outside. IAST monitors from within during QA. And RASP protects the application in production by blocking attacks in real time. Most teams start with one of these, usually SAST or DAST, and […]

Most “web application firewall comparison” articles get the question wrong. They compare vendors: Cloudflare vs AWS WAF vs Imperva vs Akamai. But those are all the same thing. They’re all perimeter-based cloud WAFs that sit between the internet and your server, inspecting HTTP traffic before it reaches your application. The better question is: where should […]
