Benefits of Vulnerability Assessment

Vulnerability Assessment service helps you to respond by identifying, classifying and addressing security risks and providing the ongoing support and guidance to best mitigate them.

Identifies at-risk assets

Gain help with identifying the systems, applications and data at greatest risk of being targeted.

Maintain trust

Benefit from a review of how well your internal and external defences detect, limit and withstand the latest threats.

Test your cyber-defence capability

Receive recommendations that will help secure your organisation now and in the future.

What Zeroday.PRO Offers

Our vulnerability assessment services identify, validate, and prioritize vulnerabilities on internet facing, internal and cloud-based IT infrastructure.

Broken Access Control

Attackers can exploit these flaws to access unauthorized functionality and/or data, such as access other users’ accounts, view sensitive files, modify other users’ data, change access rights, etc.

Sensitive Data Exposure

Many web applications and APIs do not properly protect sensitive data, such as financial, healthcare, and PII.

Broken authentification and Session management

Application functions related to authentication and session management are often implemented incorrectly, allowing attackers to compromise passwords, keys, or session tokens.

Injection flows

Injection flaws, such as SQL, NoSQL, OS, and LDAP injection, occur when untrusted data is sent to an interpreter as part of a command or query.

Security Misconfiguration

This is commonly a result of insecure default configurations, incomplete or ad hoc configurations, open cloud storage, misconfigured HTTP headers, and verbose error messages containing sensitive information.

Insecure Deserialization

The impact of deserialization flaws cannot be overstated. These flaws can lead to remote code execution attacks, one of the most serious attacks possible.

Using Components with Known Vulnerabilities

Applications and APIs using components with known vulnerabilities may undermine application defenses and enable various attacks and impacts.

Insufficient Logging & Monitoring

Insufficient logging and monitoring, coupled with missing or ineffective integration with incident response, allows attackers to further attack systems, maintain persistence, pivot to more systems, and tamper, extract, or destroy data.

How we work

Our Vulnerability Assessment Methodology

Zeroday.PRO Labs operates under a structured, repeatable methodology. We prioritize this concept in each engagement to make certain that our assessment is reliable, reproducible, and top-notch in quality. As such, our findings can always be verified by your team, before and after the remediation. To get these results, we are guided by the following steps:


Scope definition

This is where all requirements are gathered and goals are set. It’s where types of tests, forms, timelines and limitations are codified and agreed. This is essential for smooth and well-controlled exercise.


Intelligence gathering

Our security engineers use the latest intelligence gathering techniques to uncover security and technical information about the assets and applications in-scope. This information is used as attack vectors when trying to penetrate the targets during the exploitation phases.



We use a combination of public available and custom-made exploits and techniques in order to tamper with improper configurations, bypass security controls, access sensitive information and in general to establish access to the targets in question.


Reporting and Debrief

Once a security test is complete, our testers document key findings and supply prioritized remediation guidance to help address any identified exposures. Upon the completion and delivery of a penetration test, a debrief session can explain the findings and risks listed in the report

Manual vs Automated Penetration Testing

Manual Testing bring an element of human intelligence to your security efforts, and simulates the thinking and logic used by cybercriminals.

Frequently asked questions about Vulnerability Assessment

What is the main value of vulnerability assessments?

Vulnerability assessments services provided allow companies to fully realize the scope of security threats to its systems and data. As a result, a company can realize how much time and money it needs to spend to ensure its security.

What are the main security issues looked for during vulnerability assessment?

The list of main issues looked for by Zeroday.PRO specialists performing vulnerability assessment includes internal and external vulnerabilities, possibilities of unauthorized access to systems, and any other risks to the company’s infrastructure.

Should a company regularly apply for vulnerability assessments?

Yes, it’s highly recommended for companies to apply for vulnerability assessments on a regular basis. Any update or system modifications can cause the emergence of potential security flaws and, thereby, only by regularly assessing the security of its systems can companies become resistant to possible cyberattacks.
