State of xIoT

Vulnerability assessment

0%
About 50% of SEC reported breaches involved xIoT devices
50%

Assess xIoT estates for password, firmware, certificate, configuration, and device state vulnerabilities automatically at-scale.

Real-world example

Ransomware targets Healthcare organizations

In 2024, nearly 400 U.S. healthcare organizations reported incidents linked to ransomware operators like LockBit 3.0, ALPHV/BlackCat and BianLian1

State of vulnerability assessment:

attacks-are-accelerating

Attacks are accelerating

Over 820,000 IoT attacks per day were observed in 2025 — a 46% increase year-over-year. Threat actors are actively targeting connected devices at unprecedented scale.2

Unknown devices.
Unmanaged risk.

Unmanaged and misconfigured xIoT devices create security blind spots. Default credentials, outdated firmware, and poor hygiene make them easy entry points for attackers.

Breaches are costly

Breaches are costly

According to Forrester, 34% of IoT breaches result in $5–10M in losses — significantly higher than typical IT incidents due to operational disruption and downtime.3

The Phosphorus solution

Vulnerability assessment must go beyond surface scanning

01

Deep xIoT risk intelligence

Traditional vulnerability scans are notorious for misclassifying xIoT devices or just missing them altogether. Ours is purpose-built for xIoT devices and identifies default credentials in use, outdated or vulnerable firmware, end-of-life devices, insecure configurations, and expired or self-signed certificates, all with actionable context.

Exploit-aware vulnerability prioritization

02

Exploit-aware vulnerability prioritization

Not all vulnerabilities pose equal risk. Enrich CVEs with intelligence from CISA’s Known Exploited Vulnerabilities (KEV) catalog and FIRST’s Exploit Prediction Scoring System (EPSS) to prioritize remediation based on real-world exploit likelihood, not just severity scores.

03

Compliance-ready reporting built in

Simplify regulatory alignment with built-in reporting mapped to NIST 800-53, NIST 800-82, IEC 62443, NERC CIP, HIPAA, NDAA Section 889, NIS2, and OTCC. Generate audit-ready documentation while maintaining operational visibility.

Compliance-ready reporting dashboard

Not all vulnerability assessment is equal

From static CVE lists to exploit-aware risk intelligence

Traditional vulnerability tools
Phosphorus xIoT vulnerability assessment
Network scanning Network scans miss firmware-level vulnerabilities and deep device insights
Device-level visibility Deep device and firmware analysis that uncovers embedded vulnerabilities
Static severity scoring Relies on CVSS scores without real-world exploit context
Exploit-aware prioritization KEV and EPSS-enriched scoring based on real-world exploit likelihood
Credential blind spots Cannot detect default or weak credentials in use
Active credential detection Identifies default passwords and insecure authentication configurations
Lifecycle ignorance No visibility into end-of-life or unsupported devices
End-of-life risk detection Flags outdated and unsupported devices that increase exposure
IT-centric coverage Designed primarily for traditional IT endpoints
xIoT-native assessment Purpose-built for IoT, OT, IoMT, and IIoT environments
Manual compliance mapping Requires manual alignment to regulatory frameworks
Built-in compliance reporting Automated reporting aligned to NIST, IEC 62443, NERC CIP, HIPAA, NIS2, and more

Frequently asked questions

xIoT vulnerability assessment

No FAQs matched your search. Try a different keyword or topic.

Platform Overview

0

Phosphorus can discover and classify devices in minutes, not months, and does not require agents, hardware, or network changes. Organizations gain immediate visibility and can begin remediation almost immediately after deployment.

No. Phosphorus is agentless and does not require SPAN ports, taps, or additional hardware. It can be deployed on-premises, in the cloud, or in hybrid environments with minimal setup.

Discovery

0

Phosphorus currently delivers 96% precision for customers on average.

It delivers high-fidelity, device-level accuracy because it:
• Communicates directly with devices
• Collects real attributes (not inferred data)
• Profiles devices using firmware, services, and protocols

This avoids the inaccuracies common in:
• MAC address lookups
• Passive traffic analysis

Risk Remediation

0

Phosphorus provides deep risk visibility, including:
• Default or weak credentials
• Outdated or vulnerable firmware with CVE, KEV, and EPSS context
• Expired or self-signed certificates
• Insecure configurations and open ports
• End-of-life or unsupported devices

Banned or high-risk devices, including those restricted by NDAA Section 889

Yes. Phosphorus enables direct, automated remediation across xIoT devices, including:
• Password rotation and credential enforcement
• Firmware upgrades and downgrades
• Certificate replacement and renewal
•Configuration hardening, such as disabling Telnet or FTP

These actions can be executed at scale across thousands of devices with minimal operational impact.

Compliance & Zero Trust

0

Yes. Phosphorus identifies devices from restricted manufacturers, including those disguised through OEMs, white-labeling, and even unlabeled devices, and enables organizations to isolate or remediate them. This supports compliance with regulations such as NDAA Section 889.
