Rapidly Find and Fix Your Vulnerabilities
Secure Your Systems & Protect Your Assets With Our Comprehensive Testing



External Network
A simulated attack to find weaknesses in your internet-connected systems like email, file sharing, DNS, and remote access tools. This helps you strengthen your defences against online threats.
Internal Network
Testing your internal network security by simulating an attacker that has breached your external network or the actions of a malicious insider, often focusing on exploiting vulnerabilities in Active Directory.
Web App & API
Your website is a window into your business, but it can also be a door for hackers. We perform web application penetration testing to identify and help you fix vulnerabilities that could lead to data breaches or network intrusions.

Wireless Network
Wireless networks can be an easy target for hackers. We'll test your Wi-Fi security on-site, identifying weaknesses and helping you keep your data safe.

Physical Security & Social Engineering
Humans are your weak link. By testing both physical security and employee susceptibility to social engineering. Our team of ex-UKSF SRR operators, will breach your premises and manipulate employees, highlighting potential risks.
What Others Are Saying
"The pentesting uncovered weaknesses we never knew existed, and Mongoose provided clear steps for remediation. We implemented their recommendations, and I'm confident our network is now significantly stronger against Ransomware."
IT Manager, Catering Supplies
"Fantastic and personal service! Checked our business websites, services, routers and IP blocks for any potential security issues and provided very helpful feedback on the few issues identified so we were able to quickly fix. Highly recommended!"
CEO, UK ISP
"Working with animal products, we are targeted regularly for cyber attack. This was our first penetration test and we will definitely continue to use your services. The peace of mind it gives my team knowing we are more secure is worth far more than the monetary value that we pay."

Your Questions Answered
Q - Does penetration testing help with compliance requirements like GDPR and ISO 27001?
A - Yes, definitely. GDPR and ISO 27001 both have security requirements that can be addressed through penetration testing. Our tests help you identify and mitigate vulnerabilities that could lead to data breaches and non-compliance with these standards. We provide detailed reports that can serve as evidence of your commitment to data security and compliance.
Q - Why is penetration testing so important for my business?
A - Penetration testing proactively identifies weaknesses in your defences before real attackers can exploit them. This helps you:
☑ Prevent data breaches and financial losses.
☑ Protect your reputation and customer trust.
☑ Maintain business continuity and avoid downtime.
☑ Meet compliance requirements and avoid penalties.
☑ Gain a true understanding of your security posture.
Q - Why aren't vulnerability scans and automated tools enough?
A - While vulnerability scanners are helpful for identifying known weaknesses, they often miss more subtle or complex vulnerabilities. Our penetration testers use their expertise and creativity to simulate real-world attacks, going beyond automated tools to:
Exploit vulnerabilities - We don't just identify weaknesses; we try to exploit them, just like a real attacker would.
Uncover business logic flaws - Automated tools can't identify vulnerabilities related to your unique business processes.
Test for social engineering - We assess employee awareness and susceptibility to social engineering tactics.
Provide context and prioritise risks - We deliver a comprehensive report that explains the impact of each vulnerability and helps you prioritise remediation efforts. Reducing wasted time and money.
Q - You offer a 100% money-back guarantee? Are you serious?
A - Yes, we are! We're so confident in the value of our penetration testing services that we offer a full refund if you don't feel more secure after our assessment. We believe in building trust and demonstrating the real-world impact of our work. If you're not completely satisfied with the results, you get your money back, no questions asked.
