Frequently Asked Questions | FAQ

Vulnerability Assessment and Penetration Testing (VAPT) Service

Penetration testing, often called ethical hacking, is much more than a simple scan of your systems. It is a controlled, authorised attempt to break into your network, applications, or cloud infrastructure, just like a real-world attacker would. By simulating a cyberattack, our experts at Group8 can uncover exactly how a hacker might bypass your defenses and what sensitive data they could potentially reach. This proactive approach is a vital part of modern cybersecurity services, as it allows you to identify and fix critical flaws before they can be exploited by malicious actors.

For businesses, PT is necessary because it goes beyond theoretical risk. It provides tangible proof of where your security posture stands today. Whether you are looking to prevent a devastating data breach, protect your brand reputation, or ensure compliance with industry standards like HIPAA or PCI DSS, a penetration test gives you the actionable insights needed to strengthen your environment. At Group8, we take this a step further with our "Offensive-Led Cyber Defence" philosophy, ensuring that our tests reflect the actual tactics used by current threat actors.
While these two terms are often used together, they represent different levels of depth. A vulnerability assessment is a broad, automated scan that identifies a long list of potential weaknesses, such as unpatched software or common misconfigurations. It is essentially a discovery phase that provides a bird's-eye view of your risk landscape.

Penetration testing, however, takes that list of vulnerabilities and tries to exploit them. While a VA tells you that a window might be unlocked, a PT involves our engineers actually trying to climb through that window to see if they can reach the safe. This manual, in-depth simulation is focused on validating the true impact of a flaw. It is a more rigorous and labour-intensive process, but it is the only way to prove how far an attacker could actually get into your system.
At Group8, we tailor our testing approach based on how much inside information is provided at the start of the engagement. These are known as the three box models:

  • Black Box Testing: In this scenario, our testers have zero prior knowledge of your internal network, source code, or architecture. We act exactly like an external attacker, starting from the outside and trying to find a way in. This is the most realistic way to test your perimeter defenses.
  • White Box Testing: This is a transparent approach where our team is given full access to documentation, source code, and administrative credentials. This allows for a deep-dive audit of your entire security posture, including code-level vulnerabilities that might stay hidden in a traditional attack.
  • Grey Box Testing: This is a hybrid model where we are given limited information, such as a standard user-level login. It simulates an insider threat or an attacker who has already gained an initial foothold. This is often the most practical choice for many organisations as it balances realism with efficiency.
A professional engagement at Group8 follows a structured, five-stage process to ensure no stone is left unturned. This methodical approach is why we are trusted to provide some of the most reliable cybersecurity solutions in Singapore:

  • Planning:We define the scope, goals, and legal boundaries of the test to ensure we are focused on the areas most critical to your business.
  • Reconnaissance: Our team gathers intelligence on your organisation, identifying publicly accessible assets, domain names, and technical stacks to map out the potential attack surface.
  • Enumeration (Scanning): We perform deep technical scans to identify open ports, active services, and potential vulnerabilities within those services.
  • Exploitation: This is the core of the test. Our ethical hackers attempt to breach the identified weaknesses to confirm their severity and demonstrate the real-world impact of a successful attack.
  • Reporting: We compile all findings into a detailed document that includes an executive summary for leadership and technical steps for your IT team to follow.
Yes, it is. In Singapore, penetration testing is a regulated activity under the Cybersecurity Act 2018. This means that any individual or company offering these services to the public must hold a valid license from the Cyber Security Regulation Office (CSRO). This licensing framework was created to ensure that providers meet high standards of quality, ethics, and technical competence, protecting businesses from unqualified or untrustworthy actors.

Group8 has been CSRO licensed since 2022, and we take our regulatory responsibilities very seriously. By choosing a licensed provider, you gain the assurance that our methods and experts have been vetted by Singaporean authorities. This level of professional oversight is essential when you are hiring cyber security services that involve granting a third party deep access to your sensitive systems.
Absolutely. A penetration test is only truly valuable if it helps you fix the problems it finds. At Group8, our reports are designed to be an actionable roadmap for your security team.
For every issue we identify, we include:

  • A risk rating (Critical, High, Medium, Low) based on the business impact.
  • Proof of Concept (PoC) evidence, such as screenshots or logs, to show exactly how the flaw was exploited.
  • Detailed technical remediation advice, including specific patches to apply or configuration changes to make.
  • Strategic recommendations to help prevent similar issues from appearing in the future.
No, and it is important to be intellectually honest about this. A penetration test is a point-in-time assessment. It shows you how secure your systems were during the specific days we were testing. Because the threat landscape is constantly changing with new vulnerabilities discovered every day, no single test can guarantee permanent safety.

A clean report today simply means no critical vulnerabilities were found within the defined scope and timeframe of that test. To stay truly protected, you must treat security as a continuous process. This includes regular software patching, hardware updates, and layering your defenses with other tools, such as the specialised phishing detection services in Singapore provided by our Polaris platform, to protect against the human-centric attacks that a technical pentest might not cover.
The duration of a pentest can vary significantly depending on the complexity of your environment, the number of applications being tested, and whether we are looking at cloud or on-premise infrastructure. On average, a full engagement, from the initial planning meeting to the delivery of the final report, typically lasts 4 to 6 weeks.

The actual active testing phase usually takes between 1 and 3 weeks. A small web application might be tested in just a few days, while a large enterprise network with hundreds of segments could take much longer. At Group8, we work closely with you during the scoping phase to provide a precise timeline so you can plan your remediation efforts and business operations accordingly.
A Zero-Day vulnerability is a software flaw that is completely unknown to the vendor (the creators of the software). Because the vendor doesn't know about it, no patch or fix exists yet. The name comes from the fact that developers have had zero days to fix the problem before it was discovered.

While the primary goal of a penetration test is to find known vulnerabilities that you haven't fixed yet, our researchers at Group8 have the expertise to occasionally uncover unknown flaws during our deep-dive assessments. If we discover a Zero-Day, we follow a strict responsible disclosure policy. We immediately inform you and then work with the software vendor to ensure they can develop a patch, helping to secure not just your business, but the wider digital ecosystem.
