Monitor the external surface of your assets and squash vulnerabilities before they become an issue.
With new advances in technology comes new methods for hackers to take advantage of prior technology, so staying ahead of the curve is a vital part of keeping your business secure. While your internal security is vital, protecting your external security means blocking threats before they can exploit any hidden vulnerabilities.
Here is our list of the best attack surface monitoring tools:

There are several ways to keep your external security tightened, but to even approach the problem of external security, you need to know exactly what your external assets are, and what they look like, to any outsiders. This is where attack surface monitoring tools step in—by effectively producing a ‘map’ of your external surface and identifying any holes that need filling.
There are several attack surface monitoring tools, and this article goes over just nine of them. Attack surface monitoring tools come in a mixture of automated software-driven tools, and human-driven reporting tools—the best attack surface monitoring tools combine elements of both of these approaches.
- Software-driven tools provide instant and perpetual scanning and collect vast amounts of data outside the capabilities of a human team.
- Meanwhile, human-driven tools provide the personalized touch with human-readable reports that take advantage of a human’s ability to spot vulnerabilities that automation overlooks.
Another critical aspect of attack surface monitoring tools is third-party scanning. By non-intrusively performing checks on your third-party connections, these tools can identify threads that take advantage of the tools and services you rely on, to help you make informed decisions about which third-party tools to use.
