The largest businesses, government agencies, non-profit corporations, universities, and other similar sized organizations qualify as enterprises. These complex multi-location entities often deploy local networks, virtual computing environments, cloud infrastructure, and a variety of devices that classify into the internet of things (IoT) and operational technology (OT) categories. Some even deploy applications, web servers, and containers.

To examine this broad spectrum of assets and connections, these organizations need multi-faceted tools, or a vendor that can supply integrated tools that support complex workflows and larger teams for vulnerability management, remediation, and related tasks. Security teams choosing between tool options will frequently decide based upon the need for optional integrations for specific security tools or particular automation capabilities.

Fortra offers several vulnerability detection and management solutions that integrate with their security and automation solutions. Tripwire IP360 provides a focused vulnerability detection tool for both on-premises and cloud networks, including all devices and their associated operating systems and applications.

The other Fortra tools include beSECURE (available as a hosted service, an appliance, or a hybrid solution) and the Frontline Vulnerability Manager, which is part of the Frontline Cloud SaaS vulnerability management solution. Tripwire IP360 offers the most flexibility and focused capabilities of the three solutions, but organizations should select the option most appropriate for their needs.

For application scanning, Fortra offers three solutions. The BeSource SAST tool performs static application security testing (SAST), the BeSTORM DAST solution performs dynamic application security testing and black box fuzzing, and the Frontline Web Application Scanning focuses on a range of vulnerability scanning for applications within websites.

Intruder is a cloud-based vulnerability scanner that performs over 10,000 security checks. Intruder uses an enterprise-grade scanning engine to run emerging threat scans for newly discovered vulnerabilities. Results are then emailed to IT and available on the dashboard.

Intruder can perform perimeter scanning, internal scanning, cloud resource scanning, and web application vulnerability scanning. Internal scanning uses an endpoint agent.

Rapid7 Insight Platform

The Rapid7 Insight platform provides a suite of security, vulnerability management, penetration testing, web and app scanning, orchestration and automation tools to enable organizations of all sizes to secure their sprawling IT environment. Insight VM provides the vulnerability management platform to automatically scan and assess physical, cloud and virtual infrastructures. The tool provides live and interactive dashboards, solution-based remediation and risk scoring and prioritization.

Insight VM builds on the local network vulnerability tool Nexpose, and automatically detects and scans all new devices connected to a network to provide real time vulnerability identification. It also offers a lightweight endpoint agent for processing information while consuming minimal bandwidth.

The InsightAppSec tool performs Dynamic Application Security Testing (DAST) on applications and integrates into development (dev) and security (sec) workflows. The tool crawls launched applications to check for nearly 100 different attack types including SQL Injection, cross-site scripting (XSS), and cross-site request forgery (CSRF).

Developed originally as an open source and free Unix vulnerability-scanning tool, Tenable later evolved Nessus into an agentless vulnerability assessment tool with coverage for more than 47,000 unique IT, IoT, OT, operating systems, and applications. Nessus and the free version, Nessus Essentials, still exist, but enterprise-scale customers need more sophisticated solutions.

For enterprise customers, Tenable integrates Nessus with the broader Tenable One platform, which includes tenable.io for vulnerability management and web app scanning as well as the tenable.sc security center. Tenable conducts regular research and discovers zero-day vulnerabilities that it adds to the Nessus tool for early detection.

Best Enterprise Vulnerability Scanning Tool Criteria

To create this list, we surveyed a broad array of websites, vendor materials, and customer reviews to create a pool of qualified candidates based upon capabilities and reputation. We then filtered the list specifically for vendors that provide vulnerability scanning of the many different types of IT technologies and applications that an enterprise might deploy.

Similar capabilities can be achieved by combining very capable, but focused vulnerability scanners, but enterprises need tools that integrate with each other and that can be centrally managed by specialized security teams or service providers. Enterprise vendors also typically need enterprise-grade support for complex needs and issues.

Bottom Line: Buying Enterprise Vulnerability Scanning Tools

When purchasing integrated tools, it can be tempting to compare future features that could possibly be needed in 5-10 years., especially when it can be difficult to switch tools once the security team gains expertise after training and years of use on one tool.

Additionally, with enterprise-class vulnerability scanners, it doesn’t make sense to deploy multiple tools from different vendors and suffer with integration issues. Instead, open source tools should be used to provide low-cost second-opinion vulnerability scans — if the security team has the bandwidth to learn and run those tools.

Enterprise-grade vulnerability scanning tools can provide enormous return on investment by lowering the cost of IT and security teams to track, scan, and manage vulnerabilities. Still, organizations should avoid overpaying for unneeded features. Compare deployed assets against the scanning capabilities of the tools, and compare the integrations with the specific security tools already in place or options to replace existing tools.

If the tool doesn’t make sense now, future cost-savings initiatives may eliminate the tool in the future. Buy the tool needed to solve today’s problem at a price that makes sense now.
