If you need broad network and infrastructure scanning, especially on a budget, OpenVAS is a powerful, free and open-source solution — ideal for servers, network devices, and internal endpoints. If your focus is web applications and web security testing, Burp Suite (especially the Professional/Enterprise version) remains one of the most complete tools for dynamic scanning, manual testing, and deep web app vulnerability detection. Many teams use both: OpenVAS for network-level coverage and Burp Suite for application-level security.
Overview: What are OpenVAS and Burp Suite
What is OpenVAS
-
OpenVAS (Open Vulnerability Assessment Scanner) is the scanner component of the Greenbone Vulnerability Management (GVM) framework. It is licensed under GPL and free to use. Wikipedia+2The Last Tech+2
-
OpenVAS supports both unauthenticated and authenticated scanning, and covers a broad range of networked systems (servers, endpoints, firewalls, network devices). Wikipedia+2Escape+2
What is Burp Suite
-
Burp Suite, developed by PortSwigger, is a widely used web application security testing tool with multiple modules — such as proxy/interceptor, crawler, scanner, intruder, repeater, and more — designed for penetration testing and dynamic web scanning. Wikipedia+2TechTarget+2
-
It is especially tailored toward web apps, allowing testers to intercept, modify, and analyze HTTP(S) traffic, detect common web vulnerabilities (like SQL injection, XSS, CSRF), and conduct both automated and manual testing. Wikipedia+2CapSentry+2
Given their different design philosophies — network-level vs. application-level — comparing OpenVAS and Burp Suite helps you choose the right tool (or combination) for your security needs.
Key Differences: OpenVAS vs Burp Suite
Here is a comparison of the two tools based on major factors that matter when selecting a vulnerability scanner:
| Feature / Metric | OpenVAS | Burp Suite (Professional/Enterprise) | Key takeaway |
|---|---|---|---|
| Primary scope | Network, servers, endpoints, infrastructure devices | Web applications, HTTP(S) endpoints, web app logic | Use OpenVAS for network-level scanning, Burp for web apps |
| Cost & licensing | Free, open-source (GPL) Wikipedia+1 | Commercial (Community version free but limited); Pro/Enterprise paid TechTarget+1 | Budget constraint? OpenVAS wins. Web-app focus? Consider Burp paid edition. |
| Vulnerability database / Test coverage | Large database — community feed of tens of thousands of vulnerability tests (NVTs) covering many CVEs, misconfigurations, network issues Escape+2testking.com+2 | Strong in web-app vulnerabilities (SQLi, XSS, CSRF, auth issues) and combinations of manual + automated tests Wikipedia+2Diva Portal+2 | OpenVAS has broader infra coverage; Burp excels at web-app logic & HTTP-level flaws |
| Ease of use / Setup | Setup and configuration can be complex; requires some sysadmin skill Scribd+1 | More polished, user-friendly UI, easier to get started especially for web-app scanning teams G2+1 | OpenVAS might require more effort; Burp is easier for testers. |
| Automation & scheduled scanning | Supports scanning scheduling, authenticated scans, asset management via GVM | Strong for ad-hoc / manual + automated web app scans; CI/CD integration possible but more manual setup for complex scan coverage andrewgilbey.com+2TechTarget+2 | For continuous automated infra scanning, OpenVAS is great. For frequent web-app scans, Burp works well but may need manual intervention. |
| Detection rate (for web app vulnerabilities) | Limited — better suited for network, OS, service‐level weaknesses; not optimized for complex web app logic | High for web vulnerabilities; in independent benchmark found to detect 29 out of 39 known vulnerabilities in a test app Pentest-Tools.com+1 | Relying on OpenVAS alone may miss web app vulnerabilities; Burp is more thorough there. |
| Support & Community / Maintenance | Community-driven; free but may lack enterprise-level SLA and support The Last Tech+1 | Commercial tool with active maintenance, updates, and professional support for paid editions Wikipedia+1 | If enterprise-level support matters, Burp has advantage. If you accept community support, OpenVAS is viable. |
Interpretation
-
OpenVAS stands out when the goal is to scan infrastructure — servers, networks, services, endpoints — and maintain regular vulnerability assessments without licensing costs. Its extensive database and open-source nature make it a solid choice for network security teams.
-
Burp Suite, on the other hand, excels when the focus is web application security. Its ability to intercept and manipulate HTTP(S), combine automated scanning with manual penetration testing techniques, and catch complicated web-app vulnerabilities (input validation, authentication issues, logic flaws) makes it a top pick for AppSec teams.
-
In practice, many mature security programmes adopt both: OpenVAS to cover the “footprint” of network & infra vulnerabilities, and Burp Suite for the “human-facing” surface: web apps.
Use-Cases: When to Use OpenVAS, Burp Suite — or Both
✅ Use OpenVAS when…
-
You need free, open-source scanning of servers, network devices, endpoints, firewalls — especially in internal or on-prem environments.
-
You want to schedule recurring scans (e.g. monthly, quarterly) across many hosts to detect misconfigurations, outdated services, or CVEs.
-
Budget is limited or you prefer tools with open licensing, community transparency, and flexibility to customize scan profiles.
-
Your environment consists largely of infrastructure (OS, middleware, network services), not public-facing web apps.
✅ Use Burp Suite when…
-
You are performing security assessments of web applications, web services (REST, SOAP), APIs, or user-facing web portals.
-
You want the ability not only to automate detection but manually test, fine-tune payloads, and chain attacks (e.g. SQL injection + privilege escalation).
-
You care about authentication flows, session management, application logic flaws, custom input handling — vulnerabilities that network scanners typically can’t catch.
-
You need a tool with good UI, reporting, customization, and enterprise-class support (if using Pro/Enterprise).
✅ Use Both when…
-
Your organization’s attack surface spans both internal infrastructure and web applications.
-
You aim for defense-in-depth: network-level hardening + web-app security.
-
You want to build a full security programme: infra scanning with OpenVAS + regular web application pen tests or continuous scans with Burp.
Real-World Insights and Considerations
-
OpenVAS’s strength lies in its large, community-maintained vulnerability test database and ability to perform authenticated scans across many hosts, making it useful for comprehensive vulnerability management. Escape+2Wikipedia+2
-
However, because OpenVAS aims at infrastructure, OS and service-level weaknesses, it may miss web-application logic vulnerabilities (e.g. input validation, business logic flaws, session handling bugs). Diva Portal+2NORMA@NCI Library+2
-
Burp Suite remains one of the most widely accepted web-app scanning tools: a benchmark assessment showed it identified 29 of 39 known vulnerabilities in a test web application, outperforming many alternatives. Pentest-Tools.com+1
-
Setup and usability differ significantly: many security professionals find OpenVAS setup to be more complex, requiring more sysadmin work; whereas Burp Suite (especially paid editions) offers a smoother interface and workflow. Scribd+2G2+2
-
On the flipside, because Burp Suite is commercial and licensing is per-user, cost can add up — especially for large teams — whereas OpenVAS remains free and scalable. TechTarget+2Software Testing and Development Company+2
Actionable Recommendations: How to Choose + Use
-
Map your assets — classify them into “infrastructure / network devices / servers” vs. “web applications / APIs / user-facing services.” Use that classification to pick scanning tools.
-
If budget allows, deploy both OpenVAS and Burp Suite: run periodic full infra scans with OpenVAS and continuous or scheduled web-app scans with Burp.
-
Automate scanning and schedule regularly: For infra (OpenVAS), schedule weekly or monthly scans. For web apps, integrate Burp Suite into CI/CD pipelines or schedule regular penetration testing.
-
Prioritize remediation: Use results from scanners to create a backlog; treat critical CVEs (obtained results from OpenVAS) and severe web-app flaws (from Burp) differently — patch infra first, then fix application security.
-
Complement with penetration testing and manual assessments: No automated scanner catches everything — for example, business logic flaws often require manual testing. Consider regular manual pen-tests in addition to automated scans.
-
Train your team: Ensure your engineers and security team understand both tools — setup, configuration, interpreting results, and proper remediation workflows.
Frequently Asked Questions (FAQ)
Q1: Can OpenVAS replace Burp Suite (or vice versa)?
A: Not really. They serve different purposes. OpenVAS is tailored for infrastructure and network-level scanning, while Burp Suite is focused on web applications. Replacing one with the other means losing coverage in certain domains (infra or web-app logic vulnerabilities).
Q2: Is OpenVAS good enough for small businesses or personal use?
A: Yes — especially for small networks, internal servers, or home-lab environments. Because it’s free and open-source, it’s quite suitable for small budgets. However, if you host websites or web apps, you might still want a web-app scanner like Burp Suite for better coverage.
Q3: Do I need the paid version of Burp Suite or is the free one enough?
A: The free (Community) edition is useful for learning, basic proxying, and simple testing — but it lacks the full automated scanner and advanced features. For thorough web-app scanning and professional use, the paid Professional or Enterprise versions are generally needed.
Q4: How often should I run scans with OpenVAS and Burp Suite?
A: For infrastructure (OpenVAS), quarterly or monthly scans are common. For web applications (Burp Suite), it’s best to scan with every major release, or even integrate into CI/CD for continuous security testing.
Q5: What are the limitations of each tool I should watch out for?
A: OpenVAS can be complex to set up, performance may degrade on large networks, and scanning results might require manual triage.
Burp Suite, while powerful, requires some expertise to use effectively, and some advanced features are only available in paid versions. Also, like all scanners, it may not catch certain logic vulnerabilities without manual review.
Conclusion
Both OpenVAS and Burp Suite remain staples in the cybersecurity toolbox — but they excel in very different areas. OpenVAS provides free, scalable, and comprehensive infrastructure-level vulnerability scanning. Burp Suite delivers deep, flexible web application testing with both automated and manual capabilities. For organizations seeking robust security coverage — across network, servers, and web apps — the smartest move is rarely to pick one over the other, but rather to use them in tandem.
Investing in both helps ensure that you aren’t leaving parts of your attack surface unchecked. And beyond just running scans — building a strong remediation workflow, regularly patching, and combining automated scans with manual testing — is key for an effective security posture.
