	Pros & Cons from Real Users Pros Customizable Scans Wide Platform Support Pre-built policies and Templates like PCI DSS and HIPAA Frequent Plugin Updates Active and Passive Detection Comprehensive Vulnerability Coverage Nessus supports a wide range of operating systems and devices, making it versatile for diverse IT environments. Nessus benefits from an active community of users and professional support, ensuring that users can find solutions and best practices when needed. Nessus provides the flexibility to perform both agent-based scans for systems that require persistent monitoring and agentless scans for systems where installing an agent is impractical. Nessus excels at identifying vulnerabilities in systems across a wide range of platforms, including operating systems, databases, network devices, and web applications. It checks for known vulnerabilities using both signature-based and heuristic-based scanning techniques Nessus can perform configuration audits by comparing system settings against industry best practices (e.g., CIS Benchmarks, DISA STIGs). This allows organizations to enforce security policies and ensure that systems are configured securely By providing Nessus with valid credentials (such as admin-level access), it can perform more in-depth scans and accurately identify vulnerabilities that require elevated privileges. Nessus can integrate with other security solutions such as SIEMs (Security Information and Event Management systems), ticketing systems (e.g., ServiceNow, Jira), and other vulnerability management tools. This helps automate workflows and streamline vulnerability remediation. Nessus offers an intuitive user interface with a simple setup process, making it accessible even to organizations without a dedicated security team. The interface provides easy access to scan configurations, reports, and plugin management. 1) Nessus provides in-depth vulnerability scanning across a wide range of systems, applications, and devices, helping identify potential security risks quickly and thoroughly. 2) The vulnerability database is constantly updated, ensuring that the scanner detects the latest threats and vulnerabilities, which is crucial for maintaining up-to-date security. 3) The interface is intuitive and easy to navigate, even for users who aren’t security experts. It’s simple to run scans, view results, and take action based on the findings. 4) Nessus offers flexibility with customizable scanning profiles, allowing users to tailor scans to specific needs, whether it’s targeting particular systems, vulnerabilities, or compliance requirements. 5) The reports generated by Nessus are detailed and clear, offering actionable insights and prioritizing vulnerabilities based on severity. This helps teams address the most critical issues first. In depth vulnerability scanning with very usable results in easy to read formats and reports that you can drill down into. Very detailed information for how quick the scan is. Cons Limited Automation Custom Scripting Complexity No Built-In Patch Management Limited Cloud Integration False Positives The basic version of Nessus is free for limited use, accessing advanced features like compliance checks and extended reporting in Nessus Professional requires a subscription, which may not suit smaller organizations with tight budgets. Nessus scans can consume significant network and system resources, potentially slowing down operations or affecting the performance of critical systems during scans. Nessus can be resource-heavy, especially when performing in-depth scans or scanning large environments. High network bandwidth and processing power are required to perform large-scale scans without negatively impacting system performance. In environments with limited resources, this could slow down network operations or impact system stability While Nessus does offer some web application scanning capabilities (e.g., detecting SQL injection, XSS, etc.), it is not as specialized or comprehensive as dedicated web application security testing tools like Burp Suite or OWASP ZAP. Organizations with a heavy focus on web applications may find Nessus lacking in depth for these specific needs 1) While Nessus does integrate with some third-party tools, its integration options are more limited compared to some other vulnerability management platforms, which might be a drawback for larger organizations with complex IT environments. 2) Nessus can struggle with scaling up for very large, complex environments or enterprise-level networks, where more robust vulnerability management platforms might be better suited. The free trial sucked. Not only is it limited to 7 days, but you can't even try the full feature set for that 7 days. It's limited to reporting on the first 16 devices it detects. Unfortunately on my network, it didn't make it to any servers before hitting that limit, so I only got info on workstations, a printer and a credit card reader. At least give me 1 full scan of my network so I can compare workstations to servers, or give me the ability to go back and pick certain IP addresses to scan, maybe via csv file upload?
