Vulnerability Assessment Service Providers Benchmark Report Based on G2 Data

Organizations use vulnerability assessment services to identify security weaknesses and understand how to address them. As buyers compare providers, they can assess how each service fits their environment, including the systems covered, assessment methods, and post-delivery support.

These details help buyers choose a service that aligns with their security goals and internal expertise. It’s also useful to compare how providers prioritize findings, explain potential business impact, and guide teams through next steps. With a clear view of each offering, buyers can select a provider that fits the work they need done.

5. Which vulnerability assessment service providers suit a mid-sized company with no in-house security team that wants recurring scanning?

7 Layer Solutions, Cybriant and Netsurion run scanning and monitoring as an ongoing service, and buyers describe monthly scans, log monitoring and incident response handled by the provider. Testing specialists such as Packetlabs, Mithra Consulting and Appsecco deliver scheduled engagements that end with a report, which suits teams that have someone available to act on the findings.

6. Which vulnerability assessment services suit web, mobile and API testing for a team that releases often?

Security testing, Appsecco, Kaspersky Cybersecurity Services, and Packetlabs are the providers associated with web and mobile application testing. Ask whether API testing is included or priced separately, how quickly a retest can run after a fix so a release is not held up, and who explains findings to developers. Ask also how false positives from automated scanning are handled before results reach your team.

7. Which vulnerability assessment service companies do buyers describe as responsive and easy to work with?

Buyers of 7 Layer Solutions, Mithra Consulting, Netsurion, Cybriant, Appsecco and Packetlabs mention it most often. They describe quick replies to questions, availability for ad hoc requests and regular check-ins, and Packetlabs and Appsecco buyers add that the team walked them through findings. Responsiveness depends on the team assigned to your account, so ask to meet the people who would work on your engagement and agree a named contact and response time in writing.

8. Which vulnerability assessment firms give you a dashboard or portal to track results over time?

Netsurion and Cybriant buyers describe dashboards that are easy to navigate and useful for daily reporting. Buyers of testing-focused providers such as Mithra Consulting describe results arriving as emailed reports and ask for a client dashboard that shows progress over time. Ask any provider whether a portal is included and whether it tracks fix status across engagements.

9. Which vulnerability assessment providers tailor their engagements to a company's specific environment?

Buyers of Appsecco, 7 Layer Solutions, Cybriant and Mithra Consulting most often describe engagements shaped around their own environment, from plans built around certification timelines to scoping based on the buyer's use case.

10. Which vulnerability assessment services focus on network infrastructure or malware and threat intelligence work?

Juniper Services and SHI buyers mostly describe network equipment and infrastructure projects. Kaspersky Cybersecurity Services buyers mostly describe malware analysis, threat intelligence, and endpoint protection. Buyers who need vulnerability assessment alongside these services should confirm which assessment work falls inside the engagement.

Cost is the most common drawback, raised mostly by buyers of Kaspersky Cybersecurity Services and Juniper Services and by some buyers of Security testing and 7 Layer Solutions. Ask which services the price includes and which are billed separately. Juniper Services and Kaspersky Cybersecurity Services buyers also describe a learning curve and complex interfaces, so ask how much onboarding and training is included. Buyers of 7 Layer Solutions, Cybriant and Netsurion raise follow-through and account staff changes, which makes it worth asking who owns follow-up on findings and what happens when your contact changes. 

Making the final call on your vulnerability assessment partner 

Start with the work you need done. Testing specialists, managed security providers, and technology vendors each describe a different kind of engagement, so match the provider type to your project, whether that is scheduled penetration testing, audit preparation, recurring scanning, or application testing. 

Next, look at how the team works day to day. Cost, follow-through on findings, and account staff changes are the most common drawbacks. Ask who owns each finding after the report, whether retesting is included, and whether a portal tracks fix status.

Keep your shortlist to two or three providers so you can compare their answers side by side. Ask each for a sample report, a draft scope, and references from companies of your size and industry, then write the retest terms, response times, staffing, and pricing into the agreement before you sign.
