2023 Unit 42 Attack Surface Threat Report

Learn from the latest global observations.

Continuously discover, evaluate, and mitigate attack surface risk

With a complete asset inventory, discover the attack surface you didn’t know existed, find vulnerabilities before attackers and mitigate risks proactively.


Track known and unknown assets in your organization

Our ASM continuously builds and updates a record of all internet-connected assets, helping identify all exposure risks. Dive deeper and read the Cortex Xpanse Attack Surface Threat report.

  • Traditional asset inventory is slow and error-prone

    Xpanse offers a full, continuously updated inventory of assets across your organization and supply chain partners, providing a single source of truth.

  • Discovery at the speed of the internet

    Attackers scan the entire internet for vulnerabilities in 45 minutes and within 15 minutes of CVE disclosures. SecOps moves faster with Xpanse.

  • Securing the unknown

    Unknown assets make your mean time to respond effectively infinite and make attack surface reduction impossible. Xpanse finds what you can’t see.


The Most-Trusted External Attack Surface Management

Born from DARPA in 2012, Cortex Xpanse protects organizations by discovering risks on the internet that no one else can find. Our customers make up more than 12% of internet traffic.

Internet-Scale Attack Surface Management

Know your attack surface, wherever it lives

Security teams are dealing with increased complexity of multiple cloud vendors, a shifting workforce, supply chain vendors, third-party partners, and security flaws inherited through M&A. An attacker view of your attack surface leaves no blind spots.

  • Continuous asset discovery and monitoring

    Attack surfaces are constantly shifting. Xpanse scans the entire IPv4 space up to several times every day to uncover all of your internet-connected assets and keep track of changes that put you at risk.

  • Third-party risk and acquired company security

    Security flaws from supply chain partners, third-party vendors, and acquired companies put you at risk. Discover those vulnerabilities and find the relevant stakeholders to help with mitigation.

Know your attack surface, wherever it lives

Quickly discover and assign risks for remediation

Discovering security risks and quickly mitigating them is a core pillar of security. It’s a race that defenders must win because attackers are constantly searching for vulnerable targets. Cortex Xpanse ensures your asset inventory is up to date so you can mitigate exposures fast.

  • Security at internet speed

    The average organization finds two security issues per day, while attackers find one every hour. Xpanse keeps your asset inventory up to date, so you can stay ahead.

  • Stakeholders are responsible for their assets

    Mitigating threats requires knowing who is responsible for a vulnerable asset. With Xpanse, even previously unknown assets can be traced back to stakeholders to ensure fast remediation.

Quickly discover and assign risks for remediation

Build an integrated attack surface program

Integrate ASM findings into security workflows to secure unknown and unmanaged risks. This can be achieved through integration of Cortex Xpanse, Cortex XSOAR, Prisma Cloud, and our broader portfolio

  • Cortex Xpanse + Prisma Cloud

    Discover all your unsanctioned and unmanaged cloud assets and services with Cortex Xpanse and secure your unmanaged cloud with Prisma Cloud.

  • Cortex Xpanse + XSOAR

    Automate routing of exposure notifications and remediation of your unknown risks using Xpanse and XSOAR playbooks.

RDP is the most common exposure and attack vector for ransomware

Cortex Xpanse researchers found that RDP accounted for 25% of total exposures, which more than doubles the next most common exposure Unit 42 research found RDP was the initial attack vector in 50% of ransomware attacks. Find these exposures with Xpanse before they become a problem.
