Attack Surface Management (ASM)

At Censys, we can see it all. Our world-leading attack surface management platform gives organizations a sixth sense — relentlessly monitoring assets, seeing the unseen, and proactively giving security teams an opportunity to solve issues before they have a chance to take place.

This isn’t security by defense. This is a system of vigilant offense that constantly looks at everything from HTTP hosts to message brokers to remote desktop exposure to network printers. Seeking potential breaches, shoring up leaks in your protocols, and mapping any potential weak points.

Discover & Investigate Internet Assets

Including, hosts, services, SaaS logins, websites, buckets, ICS/IoT devices - regardless of cloud, ac-count, network, or location for the ultimate system of record.

Conduct Rapid Response

Rapidly identify and secure Internet assets that may be exploited by a critical vulnerability.

Prioritize & Remediate Risk

Uncover, prioritize, and remediate critical risks (e.g., potential data loss, critical vulnerabilities, exposed devices/APIs/logins) within hours of coming online.

Identify Cloud Exposure

Pinpoint weaknesses in your cloud across all providers.

Manage Acquisition, Subsidiary & 3rd-Party Risk

Understand security risk associated with uncontrolled companies — acquisitions, subsidiaries, contractors, and other dependencies.

  • Mass Scanning
    Can I get banned for mass scanning with https://github.com/robertdavidgraham/masscan or does it slow down any other vms from other persons? Source: 11 months ago
  • Has anyone ever had their homelab or network hacked? What happened?
    Nope, this doesn't work any more. Shodan checks all ports (so any attackers using data from Shodan already know which ports you have open), and tools like masscan (https://github.com/robertdavidgraham/masscan) let you portscan the entire IPv4 address space in less than 10 minutes. Source: 12 months ago
  • Private server intruded
    The discord user at the time used the tool "Masscan" to scan every 25565 port on the internet, he claims he was able to get the entire internet scanned in just a few minutes with a 512MB buyvm slice. Source: about 1 year ago
  • My home server is frustrating me. Please help me, home server wizards.
    Changing the default port does nothing for security. It only prevents some basic brute force or default password scripts. Anyone is able to scan for it in no time anyway (https://github.com/robertdavidgraham/masscan). Source: about 1 year ago
  • Should I be Concerned?
    But it should blow away the far-too-common belief that no-one's after you because you're not interesting enough. IPv4 is smaller than we think. It is not difficult to scan the entire ipv4 space in minutes. And every single one of those is going to knock your door on the way past. Source: about 1 year ago
