Vulnerability Management: 15 Tools compared

Codename Sonar is a web based reconnaissance service from Artisan Technical Computer Services, LLC, positioned for blue team work and authorised penetration testing. Users enter an IP address or web address and choose a scan profile, ranging from a ping sweep and a top 20 TCP port quick scan to intense, comprehensive, web recon, stealth and Kali recon profiles. Optional modules cover traceroute, reverse DNS, version detection, OS fingerprinting, TLS inspection, OpenVAS NVT tests, UDP probes and an analyst briefing. The Pro plan adds SIEM, CSV, PDF and STIX 2.1 exports, a watchlist and asset inventory, certificate expiry monitoring and mapping to PCI DSS 4.0, ISO 27001, SOC 2 and HIPAA. The terms of service require users to own each target or hold express, current, written authorisation to test it. An M5Stack companion device for 2.4 GHz WiFi scanning is in alpha testing.

CVETodo aggregates CVE data into a browsable database with real-time tracking and alerting. Listings carry AI analyst deep dives, remediation priority scoring, and exploit and patch status, with CISA Known Exploited Vulnerabilities tracked and a Critical Patch Now ranking ordered by remediation priority. Alongside the database it offers an open-source inventory agent for servers, agentless appliance inventory for firewalls and VPN gateways, repository scanning for dependencies, an SBOM grading tool, and remediation reports with SLA aging, benchmarked against PCI DSS, Cyber Essentials and Essential Eight. Browsing the CVE database needs no account; tracking and alerting are paid. CVETodo is an independent New Zealand business, built and run from Tauranga, founded by Anthony Walker.

GuardNest is the client platform of WorkNest Secure, the cyber security division of WorkNest that brought Pentest People, Bulletproof, and Target Defense together under one brand in May 2026. It succeeds the SecurePortal platform Pentest People was known for, and serves two purposes: delivering penetration testing engagements, with live reports, direct chat to the consultant doing the work, and remediation tracking, and running continuous vulnerability management between tests through scheduled external and web application scanning. The platform includes a threat intelligence feed, security e-learning, and integrations with Jira, Slack, and Azure so findings flow into existing ticketing and collaboration tools. It is offered in tiers: a free Essentials tier, a Core tier listed at 1,000 GBP a year covering weekly scanning of up to 50 IPs, and Advanced and Pro tiers priced on application. WorkNest Secure itself is a CREST-accredited and NCSC CHECK Green Light penetration testing provider, so GuardNest sits alongside human-led testing rather than replacing it. It suits UK organisations that already use or are considering WorkNest Secure for testing and want scanning, reporting, and retesting in one place, and is less relevant to teams looking for a standalone enterprise vulnerability management suite with agent-based internal scanning.

Microsoft Defender Vulnerability Management is Microsoft's built-in vulnerability assessment and management solution integrated into the Microsoft Defender for Endpoint platform. It provides continuous vulnerability discovery, risk-based prioritization, and remediation tracking across Windows, macOS, Linux, iOS, and Android endpoints. Leveraging the Defender for Endpoint agent already deployed in Microsoft environments, it delivers vulnerability visibility, security baseline assessment, and browser extension inventory without additional scanning infrastructure.

Qualys VMDR (Vulnerability Management, Detection and Response) is a cloud-native vulnerability management platform that provides end-to-end visibility, detection, prioritization, and remediation of vulnerabilities across hybrid IT environments. Built on the Qualys Cloud Platform, VMDR combines asset inventory, vulnerability detection, threat intelligence-driven prioritization, and integrated patch management into a single workflow, enabling security teams to move from vulnerability discovery to remediation without switching tools.

RoboShadow is a cloud-hosted vulnerability management and attack surface platform operated by ROBO SHADOW LTD, a UK company registered at Companies House under number 10726476 and incorporated on 13 April 2017. The platform combines an external scanner for internet-facing IPs and websites, a LAN scanner for internal device discovery, a web application scanner and endpoint agents that report patch level, antivirus status, encryption and firewall state. The vendor states that its Cyber Heal AutoFix function patches over 7,000 third-party applications and that the platform syncs device coverage from Microsoft 365 and Active Directory rather than rediscovering assets, and audits MFA compliance via Microsoft 365. Compliance reporting is offered against Cyber Essentials, Essential 8, NIST, SOC 2, ISO 27001 and HIPAA.

Tenable is a widely adopted vulnerability management platform, offering a comprehensive suite of products including Tenable.io (cloud-based VM), Nessus (the world's most widely deployed vulnerability scanner), and Tenable.sc (on-premises management console). Tenable provides continuous visibility into every asset across the attack surface, identifying vulnerabilities, misconfigurations, and compliance violations across IT, cloud, containers, OT, and identity infrastructure. With over 200,000 organizations relying on Tenable, it has established itself as a widely adopted standard for enterprise vulnerability management.
