External Vulnerability Scanning
Find and fix vulnerabilities in external facing assets. Proactive protection from emerging threats. Automated to save you time.
Protect your external systems with ease
New vulnerabilities are discovered daily, so even if no changes are deployed to your systems, they could become vulnerable overnight. Intruder's external vulnerability scanner makes it easy to continuously secure your systems helping you find and fix security weaknesses before they can be exploited.

Intruder’s external vulnerability scanner checks your systems for web-layer security problems (such as SQL injection and cross-site scripting), 140,000+ infrastructure weaknesses (such as remote code execution flaws), and other security misconfigurations (such as weak encryption configurations, and systems which are unnecessarily exposed).

Intruder’s external vulnerability scanner includes proactive checks for emerging threats. This means when a new vulnerability is discovered in software deployed on your perimeter, Intruder scans your systems and alerts you to newly discovered vulnerabilities automatically. This kind of proactive action is essential for businesses that don’t have processes in place to research the latest threats and manually run scans for them. Learn more.
External vulnerability scanning assesses your internet-facing infrastructure for known vulnerabilities that an attacker, who doesn’t have access to your organization's private networks, could exploit.
On the flip side, internal vulnerability scanning is concerned with finding weaknesses in your internal endpoints, which are typically hidden behind a firewall and only accessible by your employees or trusted partners.
Learn more about the differences between internal vs external vulnerability scanning.
Ideally you should do both. That being said, the majority of data breaches are caused by hackers exploiting vulnerabilities that are visible from the internet, so you want to make sure that your external systems are protected from the outset. External scanners are also able to detect multiple web-layer issues, so if you’re new to vulnerability scanning, they are often the best tools to start with.
We believe that a continuous approach is best. Continuous scanning reduces the time to find and fix vulnerabilities, delivers rich threat data and remediation advice, and minimizes your risk by prioritizing threats according to the context of your business needs. Intruder makes it easy to adopt a continuous approach. Learn more.
Yes, it’s possible to use Intruder for internal vulnerability scanning. Our internal scanner is agent-based, so you’ll need to install a piece of software on each host you’re planning to scan, either Windows, Linux or MacOS. To learn more about it, please read our help article.
