Simulating real-world attacks to strengthen your defences.
At Avella, our expert-led red teaming and penetration testing services are designed to mimic the tactics, techniques, and procedures (TTPs) of today’s most sophisticated threat actors.
By emulating real-world cyber attacks, we uncover vulnerabilities before they’re exploited — helping you build the resilience needed to defend against next-generation threats.
Our assessments go beyond box-ticking, delivering meaningful insights that enhance both protection and detection capabilities across your organisation.
We offer a wide range of technical assessments tailored to your environment.
Our Security Testing Services
From infrastructure to applications, users to cloud — our comprehensive testing services simulate real-world threats to expose and close your security gaps. Threat detection, incident response, and continuous monitoring helps protect both digital and physical assets from evolving threats.
Infrastructure Testing
We assess your internal, external, and cloud-hosted environments to uncover vulnerabilities across your infrastructure — before attackers do.
Web Application Penetration Testing
We identify and help remediate exploitable flaws in your web applications, protecting both your users and business-critical data.
Blockchain Testing Services
Our blockchain assessments ensure the integrity, security, and resilience of your distributed ledger environments, identifying risks in smart contracts and underlying infrastructure.
Mobile Application Penetration Testing
We test mobile apps across platforms to detect security gaps that could lead to data leaks, account takeovers, or unauthorised access.
Cloud Penetration Testing
Whether you're running IaaS, PaaS, or SaaS, we rigorously test your cloud stack to ensure configurations and access controls hold up under real-world attack scenarios.
Network Penetration Testing Services
We simulate attacks from both inside and outside your network to evaluate how well your infrastructure can withstand modern threats.
IoT Testing Services
From smart devices to industrial IoT, we uncover the risks that could turn your connected assets into an entry point for attackers or DDoS botnets.
Continuous Assurance
Our ongoing testing and monitoring services help you maintain real-time visibility over your cyber security posture — no surprises, just control.
External Infrastructure Penetration Testing
We test your internet-facing systems, from web apps to exposed services, identifying where attackers are most likely to strike first.
ASV Scanning
As an Approved Scanning Vendor (ASV), we help you meet PCI DSS requirements through quarterly vulnerability scans of your cardholder data environment.
Red Teaming
Simulate real-world, multi-layered cyber attacks to stress-test your defences and discover how your systems and teams respond under pressure.
Firewall Security Testing Services
We assess the configuration and resilience of your firewalls — your network's front line — to ensure they're doing more than just ticking boxes.
Purple Teaming
By fusing offensive testing with defensive insight, we help your red and blue teams work together to sharpen detection and response.
Social Engineering
We test the human layer of your security through tailored phishing campaigns and social engineering assessments — turning your team into your strongest line of defence.
Active Directory
We test your AD environment for misconfigurations and vulnerabilities that attackers could exploit to escalate privileges or gain domain control.
Bug Bounty Program
Our tailored bug bounty platform leverages a trusted community of ethical hackers — you only pay when real vulnerabilities are found.
Hybrid Testing
We test hybrid environments where Azure AD and on-prem AD are connected, identifying how compromise in one could lead to full domain takeover.
Wireless Device Penetration Testing
Our wireless testing identifies weaknesses in your Wi-Fi networks and protocols (802.11), helping secure your internal environments from rogue access.
