Invicti Web Application Security Scanner – the only solution that delivers automatic verification of vulnerabilities with Proof-Based Scanning™.

Let’s find out how you can leverage RASP to protect your applications.

The reason is obvious – rampant cybersecurity breaches across the globe, giving a hard time to individuals and businesses.

Now, applications are one of the favorite targets for cybercriminals, who are always on the lookout for finding vulnerabilities in your app. When they are successful in finding that, then God forbid, there’s a high chance they will pull off a data breach and harm you.

With such security issues around, finding an effective solution is naturally challenging.

So, what’s the solution for this?

One way of dealing with this issue is to let your apps protect themselves.


Let me put it this way, there’s a technology that goes by the name of Runtime Application Self-Protection (RASP). And using this, your applications can surround themselves with a shield that will identify and block online threats in real-time.

In this article, we are going to discuss how your apps can become self-reliant for their protection through RASP tools that will help you incorporate this technology into your applications.

Let’s start!

What is RASP?


Runtime Application Self-Protection (RASP) is the technology that comes into the picture when an app runs. And when it starts running, RASP protects it against malicious inputs by analyzing the app behavior plus the context of this behavior. It continuously monitors and detects attacks and mitigates them immediately without requiring human intervention.

RASP incorporates security onto a running app no matter where in the server the app resides. It intercepts the calls from your apps to systems to ensure they are secure and validates requests inside your app directly. It protects both non-web and web apps and never affects your app design.

A RASP software is built within or integrated with the runtime environment of an application to execute its function in protecting the app.

How does it differ from a traditional WAF?

RASP is different from a traditional WAF or web application firewall. It’s because WAFs are coupled tightly with application codes that are susceptible to exploits.

A WAF inspects all the HTTP requests incoming for attack payload as well as suspicious usage patterns, and blocks or reports the request in case it finds something wrong. But, it cannot tell how the app will process those data and might result in false positives.

Besides, modern app development has shifted towards the model of continuous deployment which leads to constantly changing attack surfaces. Hence, it becomes highly difficult for a WAF to keep pace with the approach of usage patterns.

RASP, on the other hand, enables easier deployments, provides better controls no matter what the programming language is, and performs with better accuracy. Unlike WAFs, RASP automatically adapts to any environment or language and utilizes contextual awareness to monitor threats.

Instead of any blind guesses for a payload, RASP technology detects the complete data, which sometimes may include transformed data, based on how your app will utilize it and that’s exactly what contextual means here.

RASP typically has much lower false positives as compared to WAFs. Furthermore, while a WAF provides a strong wall to secure the app on the frontline, RASP provides a robust shield to protect your app from inside out through its innovative capabilities.

Benefits of using RASP

  • As RASP makes informed decisions based on contextual detection along with rich application architecture combining static and dynamic view, there are significantly lower false positives.
  • RASP is capable of protecting your app from a variety of risks including OWASP’s top 10 vulnerabilities, injections, insecure deserialization, weak randomness, IDOR, suspicious client activity, SSRF/CSRF, and more.
  • Quick adaptability to app architectures, and can even safeguard non-web standards like RPC or XML.
  • With no blacklists, traffic rules for configuration, or learning process, RASP solutions are easy to maintain. This is why people love this, rely on it, and appreciate the time and cost it saves.
  • RASP enables cloud support. As they are self-protected, the code remains protected at all times wherever the app goes. Its configuration could be included in build scripts, generating and containerizing your application without having to update the firewall or network rules.

Now that you know about it, let’s explore some of the following best RASP solutions you can deploy to your application.


Monitor your applications and protect them against vulnerabilities and common attacks in real-time with Fortify Application Defender by Microfocus.

It differentiates between legitimate requests and dangerous threats in .NET and Java apps while protecting production apps from zero-day attacks. Its end-to-end app security solutions cover your overall development lifecycle.

Fortify offers logging visibility as well as exploit data associated with web applications in addition to line-of-code details. It also allows you to send exploit and log events to a log manager or SIEM without having to change the source code for security visibility and compliance.

You will get a robust and layered defense system that keeps your apps safe and minimizes production environment overheads. It includes 32 security rule categories that protect you from security violations including cross-site scripting, SQL injections, privacy violations, and more.

Get instant security with flexible and quick deployment without changing a single code line or any WAF training. You can control your protection from an easy-to-use and centralized management console.


OpenRASP is an open-source RASP solution from Baidu. It integrates the protection engine directly into its application server with the help of instrumentation. You can track different events like file operations, network requests, database queries, and more.

During an attack, a WAF maps malicious requests that hackers make with its electronic signature and then denies them access. But OpenRASP takes an out-of-the-box approach by hooking the sensitive functions, examining them, and blocking the inputs that are fed into the functions.

This procedure offers benefits such as:

  • Allows only the successful attacks to trigger alarms, hence, resulting in fewer false positives along with a better detection rate
  • It makes forensic analysis faster and easier due to detailed logging of stack trace
  • Insusceptible to misinformed protocols

You can also get some test cases that directly correspond to OWASP TOP 10 cyberattacks. OpenRASP works well on Java and PHP. It integrates with existing SOC and SIEM and logs alarms in JSON, which is easy to pick up by log collectors such as Flume, rsylog, and LogStash.

Signal Sciences

The easy-to-install software of Signal Sciences supports various programming languages and frameworks, including PHP, Scala, Perl, Node.js, Python, Java, Go, .NET, and Rails, and protects them from attacks while maintaining their performance. It can integrate into a DevOps toolchain product for wider, cross-team visibility.

Signal Sciences protects 40k+ apps per year on average, has managed to provide great customer service, and supports 100+ multi-cloud and hybrid platforms.

It is one of the market leaders when it comes to RASP due to its reliability, operational manageability, scalable protection, and various deployment options no matter where your application operates.

You will get protection far beyond Top 10 OWASP vulnerabilities including bad bots, account takeover, app DDoS, API abuse, and more. It supports multiple architectures from an application native to legacy applications, serverless, and containers. As they provide a hybrid-SaaS solution, you can deploy it into your apps directly with only one DNS change, requiring no agents.

Self-serve security insights and alerts help you solidify your security posture and remain proactive always.
