    Our approach

    We live in a world of constant cyber threats. Almost every organisation relies on interconnected applications and APIs, making themv targets for attackers. The threat landscape evolves rapidly; we’re no longer dealing with simple viruses, but advanced persistent threats.

     

     

    Veracode research highlights that the average time to fix security flaws is 252 days, and 50% of organisations have critical vulnerabilities unaddressed for over a year. Traditional remediation is challenging - fixing vulnerabilities requires significant resources many teams lack.

     

     

     

    The challenge with traditional patching

    In an ideal world, as soon as a software vulnerability is discovered, the vendor's patch would be applied or push a code fix and the problem would disappear. In reality, patches get delayed or prioritized down, and vulnerabilities linger. The U.K.’s NCSC said it best: patching is “time-consuming, repetitive and unrewarding, but it is the single most important thing you can do to secure your technology.” Yet many organizations struggle to keep up. A 2024 report highlights that nearly 60% of cyber compromises were attributed to unpatched vulnerabilities. Finding vulnerabilities is only half the battle – fixing them in a timely manner is the real challenge.

     

     

     

    The race against attackers

    While organizations find it difficult to remediate quickly, attackers are moving faster than ever. Research from Kenna Security shows that over 50% of exploits are available within one day of a vulnerability’s disclosure, and 75% within a month. In other words, the window between a new bug being announced and it being actively weaponized is now incredibly short – often shorter than an organization’s patch cycle. In fact, attackers don’t even wait for official disclosures; once a CVE is reserved, they may start developing exploits before a vendor patch exists. This “speed of war” being less than a day means that unless you can mitigate or fix vulnerabilities almost immediately, your organization is at risk in that gap period.

     

    A new approach – in-flight security patching

    RedShield was born out of this urgent need to fix known vulnerabilities more quickly. Its founders – experts in penetration testing and enterprise security – saw time and again that clients were stuck accepting the risk of known flaws (especially in legacy systems) or disrupting their business to have developers rush out a fix. They knew there had to be a better way. RedShield’s answer is in-flight security patching: deploying a real time fix for an application vulnerability so the issue is effectively resolved without modifying the application itself.

     

    What is an in-flight security patch? It’s a small piece of code that runs on RedShield’s AWS-powered platform that is designed to fix an otherwise exploitable flaw in your application. When a vulnerability is identified, our engineers pinpoint the trigger conditions in the app’s traffic – the specific requests or data that would exploit the bug. They then develop a custom in-flight patch that intercepts those malicious inputs or responses and neutralizes them. We have a library of over 14,000 such patches built from years of experience, so more often than not, we can deploy a ready-made fix immediately. If not, our team can craft a new patch quickly - even within hours. These in-flight patches alter or sanitize traffic in real time, making the vulnerability non-discoverable and the exploit ineffective. Importantly, this all happens without touching your application’s source code – we don’t even need access to it. Our patches work externally, which means we can protect third-party applications, or systems no longer supported by developers.

    Benefits of in-flight security patching

    Solving the people and resource problem

    There’s a worldwide cybersecurity skills shortage. Even if you have the right scanning tools, you might not have enough qualified staff to analyze results and implement fixes quickly. RedShield addresses this by combining technology and expert service. Our team of application security engineers operates 24x7 as an extension of your team. They continuously scan your applications, monitor for threats, and when a vulnerability is found, they write and deploy the necessary in-flight patch to secure it. Because cyber threats don’t wait, our experts are always on call. We bring the hard-to-find skills and around-the-clock vigilance, so you don’t have to hire and train a large in-house staff to manage application security.

    Addressing complex vulnerabilities

    Modern applications are complex, composed of many moving parts and third-party components – which means a huge attack surface. Effective defense needs to be multi-layered and intelligent, not just one-size-fits-all. In-flight patches allow very targeted, logic-driven remediation for complex issues. For example, an in-flight patch can enforce specific input validation, rewrite parts of responses, or integrate with external verification services – whatever is needed to nullify the exploit. This level of specificity handles cases that generic tools miss or are too blunt to fix. By deploying these in-flight patches, RedShield protects your vulnerable applications from waves of cyberattacks and buys you time until a permanent code or product update is available.

    Securing cloud applications with ease

    Every cloud provider outlines a shared responsibility model – they secure the underlying cloud infrastructure, but you must secure your applications and data in the cloud. For many organizations, fully meeting that responsibility internally is daunting. The effort to assemble and maintain an in-house program – stitching together WAFs, DDoS protection, bot management, patches, etc., and keeping them tuned – is enormously expensive and can take years to mature. RedShield offers an affordable and highly effective alternative: a turnkey cloud-based security service for your applications.  Our experts apply best-of-breed tools and custom in-flight patches to protect your cloud deployments, so you don’t have to build that capability from scratch.
