XSScanner imitates a real-world penetration tester. From identifying a potential injection point to providing a detailed, well-written report.
Whether you're a defender or attacker, you want this tool as your co-pilot.

Simulate a pentester
Simulate a penetration tester's behaviour by performing a series of tests to identify and exploit a cross-site scripting vulnerability.
Latest WAF bypasses
A payload set that includes XSS payloads ranging from basic to advanced to the recently discovered web application firewall bypasses.
Instant Notifications
Receive notifications immediately once XSScanner discovers a cross-site scripting vulnerability. Even when your vulnerability scan is still running.

REDIRECT X screenshot



Like the XSScanner, Redirect X simulates an actual penetration tester's testing procedure. And it shows.
Redirect X is capable of finding context-based, multi-step, Server-side, POST-based and DOM-based redirects. With low to zero false positive results (as all our tools are).

Simulate a pentester
Simulate a penetration tester's testing procedure by performing a series of tests to identify and exploit a cross-site scripting vulnerability.
Advanced payload set
Evade strict, context-based filters with our personalised wordlist generated for each new scan.
Instant Notifications
Receive notifications immediately once Redirect X discovers an open redirect vulnerability. Even when your vulnerability scan is still running.

CORScanner is capable of finding high-level CORS misconfigurations that could be exploited by bad actors to gain access to private user data.

Simulate a pentester
Simulate a penetration tester's behaviour by performing a series of tests to identify and exploit a cross-origin resource sharing misconfiguration.
Advanced pattern bypasses
A set of payloads that are used for bypassing most common cases of loosely-set regex patterns but also more advanced cases (including forgotten third-party whitelisted domains).

  1. @lu3ky13Lu3ky13 ⚡️⚡️

    I liked the timed scanning & scheduling

  2. @Thee_EclipseThee Eclipse

    The website is awesome, gives a great visual analysis of the target, and is comprehensive in recon and efficient, especially the Spider X. Timely notifications and a user has full control of their account

  3. @thedaniuxxDanny

    I am using novasec for recon and I am very happy with it, it is easy to use, plus it has some very interesting tools that I have not seen elsewhere, highly recommended.

  4. @HawkEye00888713Hawk_Eye

    This tool is marvelous for recon subdomain gathering and content discovery with very fast output and I really liked that.

  5. @falcon_charan0xcharan

    I recently had the opportunity to try out the Nova Security service and I must say, I was thoroughly impressed with its XSS tools and open redirect functionality. What sets Nova Security apart from other similar services is its unique approach of checking for reflection before crafting payloads.

Got questions? We're here to help.

Vulnerability scanning is a process where an automated program is looking for vulnerabilities and security misconfigurations in your web application or network.

Usually, vulnerability scanners execute a predefined workflow to identify any exploitable vulnerability type.

Once a vulnerability scanner has found and verified a valid security flaw, it creates an alert and reports the finding accordingly.

This truly depends on how big and complex your web application or API is and your scan configuration.

You can perform as many scans as you want but we do have some limitations on the number of concurrent (parallel) scans. Check out our pricing plan for more information.

You can scan your web application as many times as you want.

However, we do recommend you at least scan your web application each time you push new code.

Throughout our years of experience as web app penetration testers and bug bounty hunters

We sometimes used third-party vulnerability scanners to automate some of our workflows, and it didn't work out well for us.

We had times when we found vulnerabilities while some vulnerability scanners just couldn't, even after pointing out where to scan.

This never allowed us to put our trust in vulnerability scanners. And we found that this should change.

Today, Nova Security is capable of finding vulnerabilities in various contexts, vulnerabilities that otherwise would've been left undetected by other scanners.

That is one key element that sets us apart from our competitors. It's our unfair advantage.

Nova Security provides an API in place for you to use in your development cycle.

This will allow your team to fully automate the vulnerability scanning process.

Yes, we even encourage you to do so to uncover any hidden security flaws that may have had devastating effects if they're left untouched.

No. We give you the option to set a rate limit to not put excessive load on your server.

If you have signed up as a security researcher or bug bounty hunter, by default, when you enable monitoring for a project. We save the data to track changes and to notify you accordingly.
This is necessary as else, we won't be able to know what new assets have been added.
However, you always get the option to permanently delete any project data from our database.

If you registered as a business, we provide you with a pre-set timeframe to export your scan results.
After the timeframe has elapsed, we permanently delete any data on our databases to keep your online business safe.

In general, we do not collect any data as we run our own scans to provide you with our services.
If this happens to change in the future, we will anonymise any data and will always include the option to allow you to opt out at any time.
