Our Services

Types of Penetration Testing

At ONSec, we offer a variety of penetration testing that will meet the needs of your business to ensure that you remain compliant with any regulatory authorities.

Network and Infrastructure Penetration Testing

Secure networks and infrastructure is the backbone of your business cyber security.


Regular internal and external penetration testing is essential to identifying vulnerabilities and mitigating the risk of breaches helping to avoid costly incidents before they occur.

External penetration testing, conducted remotely by our ethical hackers, allows your business to proactively strengthen its cyber security by addressing high-risk vulnerabilities and exposure before they’re exploited.

Web Application Penetration Testing

Web applications are central to modern business operations and a prime target for cybercriminals.

 

Our web application penetration testing services proactively identify vulnerabilities that could lead to the exposure of sensitive data, such as user credentials and financial information.

 

Regular testing is essential to maintaining a strong security posture and reducing the risk of data breaches.

Cloud Penetration Testing

Securing your cloud environment requires more than traditional testing it demands a cloud first strategy.

 

Unlike infrastructure focused assessments, cloud security assessments concentrate on evaluating the management plane, the control layer that governs your cloud resources.

At ONSec we specialise in a tailored assessment that goes beyond surface level scans. By combining automated tools with manual analysis, we identify all deployed services and expose misconfigurations, control gaps, and potential weaknesses that could lead to exploitation.

API Penetration Testing

APIs are the backbone of most modern applications. However they also present unique security challenges.

Our API penetration testing service identifies vulnerabilities that could allow attackers to bypass authentication, access sensitive data, or compromise backend systems.

Using a combination of automated scanning and  manual testing, we assess your APIs against industry standards such as OWASP API Security Top 10. We simulate real-world attack scenarios to uncover vulnerabilities and limit your exposure to these.

WiFi Penetration Testing

Wireless networks are often the weakest link in a business's network offering attackers a potential entry point without ever stepping inside your building.

 

Our WiFi penetration testing service identifies vulnerabilities in your wireless infrastructure before they can be exploited.

We assess the security of your wireless environment through controlled, real world testing.

Mobile Application Testing

Mobile applications are a prime target for cyber attackers, often containing sensitive user data, payment details, and access to backend systems.

 

Our Mobile Application Security Testing service is designed to uncover vulnerabilities in both iOS and Android applications before they can be exploited in the wild.

Our testing methodology aligns with OWASP Mobile Top 10 and industry best practices, ensuring a thorough and standards based assessment to ensure that your mobile application remains secure and compliant.

Testimonials

Here at Miles Macadam, working for both the Private and Public sectors, we found that we were increasingly being expected to hold Cyber Essentials certification right from the point of tendering for potential work. We were initially daunted by this as IT, and particularly IT Security, are so far outside of our core skills that we had no idea where to start.

 

We needn’t have worried though as Pete was able to take us through the process smoothly and efficiently – handling it with the ease you would expect from a professional provider. We are now in our second year of certification, and the renewal was just as straightforward.
