Why Is Vulnerability Assessment As A Service Important?


Vulnerability assessment as a service is typically more cost-effective than maintaining an in-house security team to perform the same function. This is particularly true for smaller organizations that may not have the resources to maintain a dedicated security team.


Cybersecurity assessment services can be scaled up or down as needed, allowing organizations to adapt to changing needs and budgets. This flexibility allows organizations to perform assessments on a regular basis, ensuring that their systems remain secure over time.

Risk management

Vulnerability assessment companies help organizations to manage their risk by identifying potential vulnerabilities before they can be exploited. This proactive approach can help to prevent security breaches and other incidents, reducing the risk of data loss, financial loss, and damage to reputation.


Many regulations and industry standards like HIPAA, PCI-DSS, GDPR and more require organizations to perform regular vulnerability assessments. This can help organizations meet these requirements and maintain compliance with relevant standards.

How To Choose A Good Vulnerability Assessment Company?

Here are some factors to consider when selecting a vulnerability assessment company:

1. Reputation

Look for a company with a strong reputation in the industry and extensive experience in vulnerability assessment. Look for reviews and testimonials from past clients, and research the company’s history and track record.

2. Qualifications

Check the qualifications and certifications of the company’s security professionals, such as Certified Information Systems Security Professional (CISSP), or Offensive Security Certified Professional (OSCP). These certifications indicate that the company has the necessary knowledge and expertise to perform effective vulnerability assessments.

3. Methodology

Look for a company that uses a rigorous, well-documented methodology for vulnerability assessment. The methodology should be based on industry best practices, such as OWASP Top 10, NIST or the Common Vulnerability Scoring System (CVSS).

4. Tools 

Evaluate the company’s tools for vulnerability assessment. The company should use the latest and most effective tools like vulnerability scanners for identifying vulnerabilities and should have the capability to perform both automated and manual testing.

5. Reporting and Remediation 

Look for a company that provides clear, comprehensive reports detailing the vulnerabilities identified, their severity with actionable risk scores based on CVSS scores, and recommended remediation strategies. The company should also be able to provide guidance and support for addressing the vulnerabilities identified.

6. Compliance

Check if the company has experience working with compliance and regulatory requirements relevant to your industry, such as GDPR, ISO 27001, SOC2, HIPAA, or PCI DSS.

Limitations of Vulnerability Assessment Services

While vulnerability assessment services can provide valuable insights into potential security vulnerabilities, there are some limitations to be aware of:

  1. False Positives

Vulnerability assessment tools can sometimes generate false positives, indicating that a vulnerability exists when it does not. This can lead to wasted time and resources investigating and addressing non-existent vulnerabilities.

  1. Missed Vulnerabilities 

Similarly, vulnerability assessment tools may miss certain vulnerabilities, leading to a false sense of security. This is particularly true for vulnerabilities that are difficult to detect, such as zero-day exploits or advanced persistent threats.

  1. Limited Scope

Vulnerability assessments are typically limited in scope, focusing on a specific system, network, or application. This means that they may miss vulnerabilities in other parts of the organization’s infrastructure.

  1. Security Not Guaranteed

Even with a vulnerability assessment, there is no guarantee that an organization’s systems and data will be completely secure. Attackers are constantly developing new tactics and techniques, and organizations must remain vigilant and adaptive to stay ahead of evolving threats.
