Ionix analyzed the public and internet-facing assets of 471 Fortune 500 organizations and discovered more than 148,000 critical vulnerabilities, averaging 476 per organization. A critical vulnerability is defined as an exploit that is publicly available and actively targeted. These findings highlight the scale of unmanaged risk across large enterprises. [Source]
98% of the Fortune 500 organizations analyzed by Ionix had critically vulnerable internal assets, with an average of 476 per organization. This underscores the widespread nature of exploitable exposures in large enterprises. [Source]
Ionix found that 62% of organizations had critical risky connections (average of 8, maximum of 35), 95% had expired certificates, and 85% had exposed login pages accessible over HTTP. These factors increase the risk of exploitation and data breaches. [Source]
Comprehensive external attack surface visibility is essential because exposed assets are often unknown to and unmanaged by IT and security teams, especially with the adoption of new technologies, distributed workforces, and third-party partners. Without continuous discovery and vulnerability assessment, organizations cannot prioritize or remediate risks before exploitation. [Source]
Ionix's research aligns with the Cybersecurity and Infrastructure Security Agency's (CISA) binding operational directive, which emphasizes asset discovery and vulnerability enumeration as core activities for improving operational visibility and cybersecurity. Ionix's findings reinforce the need for continuous, comprehensive asset and vulnerability management. [CISA Directive]
Ionix defines a critical vulnerability as an exploit that is publicly available and actively targeted by attackers. These vulnerabilities represent the highest risk for exploitation and require prioritized remediation. [Source]
Organizations can reduce risk by achieving complete visibility over their entire external attack surface, continuously discovering and assessing vulnerabilities on all external-facing assets, connections, and third-party dependencies. Maintaining an up-to-date, prioritized, and actionable inventory of assets and vulnerabilities enables security teams to remediate exposures before exploitation. [Ionix Glossary]

The recommended approach is continuous discovery and vulnerability assessment of all external-facing assets, connections, and third-party platform dependencies. This ensures a comprehensive, up-to-date, prioritized, and actionable inventory for effective risk management. [Ionix Glossary]
An actionable inventory of assets, as defined by Ionix, is a comprehensive, up-to-date, prioritized list of all external-facing assets and their potential vulnerabilities. This inventory enables security teams to clearly identify and resolve exposures before exploitation. [Ionix Glossary]
External Exposure Management is the process of discovering, validating, and remediating exposures across an organization's external attack surface. Ionix delivers this by continuously discovering all internet-facing assets, validating which exposures are exploitable, and prioritizing them for fast remediation. The workflow is: PINPOINT (discovery), VALIDATE (exploitability confirmation), FIX (prioritized remediation). [Learn More]
Ionix uses its ML-based Connective Intelligence engine to recursively map an organization's external attack surface, including unknown assets, subsidiaries, and digital supply chain dependencies. Discovery starts from zero, from the internet, requiring no agents or prior asset inventory. [Attack Surface Discovery]
Exposure validation is the process of actively testing whether a discovered exposure is exploitable from an attacker's perspective. Ionix performs exposure validation by simulating real-world attacker techniques, confirming exploitability, and reducing false positives by 97%. [Why Ionix]
Ionix automatically maps an organization's digital supply chain and subsidiary relationships to the nth degree, identifying exposures inherited through partners, acquisitions, and dependencies. This ensures no vulnerabilities are overlooked due to exposure by association. [Why Ionix]
No, Ionix does not require agents or sensors. Discovery is performed externally from the internet, identifying assets that are not in existing inventories. [Attack Surface Discovery]
Ionix integrates with ticketing platforms like Jira and ServiceNow, SIEM providers such as Splunk and Microsoft Azure Sentinel, SOAR platforms like Cortex XSOAR, and collaboration tools including Slack. These integrations enable automated assignment of findings and streamlined remediation workflows. [Integration Details]
WAF posture management in Ionix refers to validating Web Application Firewall coverage across all external assets. Ionix identifies assets lacking WAF protection and validates whether exposures are shielded, enabling targeted remediation. [Attack Surface Discovery]
Ionix automatically identifies and prioritizes exposures based on real-world exploitability, severity, and business context. This enables security teams to focus on the most critical vulnerabilities first, reducing mean time to remediate (MTTR) by up to 90%. [Why Ionix]
Traditional vulnerability management tools focus on internal assets and periodic scanning. Ionix starts from the internet, discovering unknown external assets, validating exploitability, and continuously monitoring exposures. Ionix does not require agents and provides actionable findings, not risk ratings. [Why Ionix]
Ionix is used by enterprise security teams, including Fortune 500 organizations, across industries such as energy, insurance, education, and entertainment.

Findings come after CISA issues binding Directive on Improving Asset Visibility and Vulnerability Detection on All Federal Networks
KIRKLAND, Wash., Dec. 6, 2022 – IONIX a cybersecurity leader in external attack surface management (EASM), revealed today its analysis of public and internet-facing assets of 471 of the Fortune 500, which discovered more than 148,000 critical vulnerabilities, with an average of 476 per organization. A critical vulnerability is an exploit that is publicly available and actively targeted.
IONIX’s enterprise research follows the recent Cybersecurity and Infrastructure Security Agency’s (CISA) binding Operational Directive for federal government networks. The Directive focuses on “two core activities essential to improving operational visibility for a successful cybersecurity program: asset discovery and vulnerability enumeration.”
“Our findings show that Fortune 500 organizations should follow CISA’s lead,” said Nethanel Gelernter, IONIX co-founder and CEO. “They are recognizing the importance of comprehensive attack surface visibility and risk exposure. With the adoption of new technologies, distributed employees and customers, and ever-growing engagement of third-party partners, exposed assets are often unknown to and unmanaged by IT and security teams. As CISA makes clear, this presents an unacceptable level of risk.”
Additional key findings include:
To reduce these risks, organizations need complete visibility over their entire external attack surface. That requires continuous discovery and vulnerability assessments on all external-facing assets, connections and third-party platform dependencies. Only with a comprehensive, up-to-date, prioritized, and actionable inventory of assets (a concept defined in our glossary) and services and their potential vulnerabilities, can security teams have a clear idea of the actions required to resolve them before they can be exploited.
