Web application pentest
Applications, APIs & web services
- Web applications & APIs
- Exploitability & impact
- CVSS with business context
We identify and exploit vulnerabilities in web applications, APIs, and web-based services to uncover flaws that could compromise data or disrupt operations.
Our business-centric approach ranks each finding by exploitability and real impact. We enrich industry-standard CVSS with our own categorization to build a tailored remediation roadmap aligned with your business priorities.
Discuss your scopeMobile app pentest
iOS, Android & connected backends
- iOS & Android
- Storage & authentication
- Backend & third-party components
We evaluate iOS and Android applications, their backend components, APIs, and interactions with devices and servers.
Following our intelligently tailored approach, we investigate data storage, authentication, and third-party components to uncover hidden vulnerabilities and help protect the infrastructure behind your mobile experience.
Discuss your scopeInfrastructure pentest
Internal networks, systems & segmentation
- Assumed internal foothold
- Servers & workstations
- Network segmentation
Starting from an assumed internal foothold, we evaluate servers, workstations, network services, and segmentation to expose weaknesses in the environment.
We challenge what is presumed safe and sound, turning configuration flaws and attack paths into actionable steps to strengthen your systems and cyber resilience.
Discuss your scopeEnterprise pentest
Your external digital footprint, end to end
- External attack surface
- Connected attack paths
- Business-wide risk
A comprehensive engagement that simulates a large-scale external attack across your organization’s digital footprint, assessing defensive capabilities against persistent attackers.
We connect exposures and attack paths across your value chain to reveal systemic weaknesses and critical business risks. The result is a clear, prioritized view of where to strengthen defenses, protect your brand, and improve your organization’s security.
Discuss your scopeAI pentest
AI applications, agents, RAG & infrastructure
- AI applications, models & agents
- RAG, data & access controls
- AI infrastructure & integrations
We assess AI-powered applications, models, agents, and RAG solutions, together with the infrastructure behind them: model endpoints, APIs, vector databases, data sources, and connected tools.
Within an agreed scope, we test prompt injection, sensitive data exposure, retrieval and access-control weaknesses, unsafe output handling, and excessive agent permissions. We connect findings to real business impact and deliver prioritized remediation guidance for your AI systems.
Discuss your scopeRed team
Adversary simulation & detection readiness
- Threat actor TTPs
- Objective-led operations
- Detection & response
An objective-led test of your organization’s cyber resilience. We emulate the tactics, techniques, and procedures of sophisticated threat actors to test your defenses against realistic attack scenarios.
We chain weaknesses, move laterally, test evasion, and escalate privileges within agreed rules of engagement. The outcome shows how well your defense team can detect, investigate, and stop an adversary before critical business objectives are compromised.
