We see your web applications through an attacker's eyes.
The complexity of software development makes web application vulnerabilities a prime target for cyber attacks. BlackstoneOne's Web Application Scanning detects vulnerabilities in real time as they are discovered, to keep you safe and save you time.

Web application scanning
Continuously identify vulnerabilities in your web applications before attackers do.
Your web applications are often the primary entry point for cyberattacks. BlackstoneOne continuously scans your internet-facing web applications to identify vulnerabilities, security misconfigurations, outdated components, weak encryption, insecure headers, and other security weaknesses that could expose your business to risk. With automated assessments and actionable findings, you gain a clear overview of where to focus your remediation efforts first.
Continuous vulnerability assessment
Unlike point-in-time testing, BlackstoneOne continuously evaluates your web applications to detect newly introduced vulnerabilities as your applications evolve. Every finding is prioritized by severity and business impact, helping your team remediate the most critical risks first.
Actionable security insights
Every identified vulnerability includes technical details, risk severity, remediation guidance, and historical tracking, enabling your teams to measure improvements over time and continuously strengthen the security of your web applications.

What we scan
The vulnerabilities most commonly exploited in web applications.
An attacker can gain unauthorized access to an application's database through an SQL injection vulnerability, putting your data at high risk. We identify these entry points before attackers can exploit them.
Injected scripts that run in a visitor's browser, used to hijack sessions or steal data. A common and frequently exploited web application weakness.
Weak session management and insecure login flows that let attackers impersonate legitimate users or gain unauthorized access.
BlackstoneOne detects new vulnerabilities in real time as they're discovered, rather than waiting on a periodic scan, so exposure windows stay short.
Black-box scanning
We test your application the way a real attacker would.
BlackstoneOne’s web application scanning is unauthenticated by design. We never request or store credentials for your application, so there’s no risk of exposing login details or disrupting logged-in user sessions. The scan starts from the same position a real external attacker has: the URL, nothing more.
Black-box testing
No source code, no credentials, no insider access. Just the public URL, the same starting point as a real attacker.
BlackstoneOne's approach
Crawls the full public-facing surface of your application, testing for injection, broken authentication, and other exploitable flaws, without ever handling your login credentials.

Frequently asked questions
Common questions about Web App Vulnerability Scanning.
Is Web App scanning different from External Vulnerability Scanning?
Yes. External scanning covers your network perimeter: IPs, ports, and services. Web app scanning goes deeper into how your application itself behaves. When a URL scan is run in BlackstoneOne, both a web application scan and an infrastructure scan are performed at the same time, so you don't have to manage two separate processes.
Do you scan behind logins using my credentials?
No. BlackstoneOne's web application scanning is unauthenticated (black-box) and never requires or stores your credentials. We test the full public-facing surface of your application, the same access point a real external attacker has.
How quickly will I see results?
Vulnerabilities are prioritized by risk, threat, and context, and can be sent directly to your team within hours of a scan completing. Try it with a 30-day free trial.
