One library to supercharge your app security

Sqreen dashboard

Prevent vulnerabilities that put your app at risk

Your application can now stress itself at run-time. Catch critical vulnerabilities in the code before deploying to production. Prioritize your security efforts and focus on what matters.

Sqreen dashboard

Protect your production in real-time

Supercharge your app security with our security library that blocks attacks targeting your production app. The main attack categories are covered: XSS, Injections (SQL, NoSQL, Shell) etc.

Sqreen dashboard

Fix your code easily

Get actionable data and stack traces to easily fix critical vulnerabilities uncovered by Sqreen, attackers, pentesters or bug bounties. Fix them and get back to the fun stuff.

Sqreen dashboard

Monitor your app threat level

Always stay one step ahead of attackers. Get faster insights on suspicious activities in real-time. Don’t rely on logs and reduce alert noise.

Sqreen dashboard

Avoid data theft and fraud

Identify suspicious user behaviors in real-time (suspicious connections, geolocations and more). Protect your users data and avoid account takeovers.

What’s your excuse?

I’m too busy

Sqreen is just another library to install in your app. Get started in under 3 mins. No code changes, heavy configuration or maintenance required.

I’m not a security expert

Sqreen makes it easy to secure your apps from development to production by focusing on what matters and removing alert noise.

I need enterprise-grade performance

Sqreen is extremely high performant: virtually no performance impact and no CPU or memory overhead. No single-point of failure. The protection doesn't rely on the network

I’m afraid you will break my app

Sqreen blocks attacks, not your legitimate traffic. We don't generate false positives and 90% of our customers use Sqreen in full-blocking mode

I have strong privacy concerns

Your data belongs to you. The protection logic and sensitive data stays inside your app. No traffic redirection and no PII collected.

I don’t trust you

Our team has played lead security roles in companies like Apple or Airbus and our investors and amazing clients (Mindbody, Algolia, Toptal and more) trust us. Why shouldn't you?

One library to rule them all
