Boutique Penetration Testing

With 15 years of experience and hundreds of projects behind us, we’ve developed a boutique approach to penetration testing. We work on one project at a time to go deep, focus fully, and find the critical security issues that could seriously impact your business.

Commitment That Sets Us Apart
One project, one dedicated team icon
One project,
one dedicated team
We commit to a single engagement at a time.
Your assessment is handled by a focused team
with no parallel assignments, ensuring deep
attention and complete alignment with your
security objectives.
In-depth assessment beyond the scope icon
In-depth assessment
beyond the scope
Our team is trained to think like attackers.
If critical risks emerge outside the original scope,
we escalate and investigate — because
business threats rarely stay confined
to a predefined boundary.

Industries

Finance
  • Required by PCI DSS, SOC 2, AMLD, DORA, and other strict financial compliance frameworks
  • Focused on business logic abuse: transactions, payouts, rate manipulation, and fund diversion
  • Simulates user-centric threats: credential stuffing, client-side exploits, and API abuse at scale

From Revolut’s data breach to Robinhood’s support system hack—financial platforms bleed fast and publicly.

Pentesting isn’t optional in fintech—it’s margin protection in disguise.

Finance industry
iGaming
  • Targets of constant attack: from account takeovers to game rigging and payment fraud
  • Aligned with UKGC, UIGEA, AML, and other global betting regulations
  • Includes deep white-box audits of third-party platforms and white-labeled

iGaming platforms are goldmines for attackers—pentesting keeps the odds in your favor.

Average breach cost? $10M. One hidden flaw can take down your license.

iGaming industry
Online Games
  • Attackers target cheats, dupes, account takeovers,
    and in-game economy exploits
  • Covers compliance: GDPR, AMLD, DORA, PCI DSS — yes,
    even game studios are in scope
  • Finds token abuse, currency inflation paths, and real-money trading backdoors

From EA account hijacks to Diablo gold dupes, the industry’s been burned.


Pentesting ensures your game isn’t next.

Online Games industry
SaaS Platforms
  • Attackers hunt for broken auth, tenant leaks, and privilege escalation paths in multi-user environments
  • Covers SOC 2, ISO 27001, GDPR, and rising enterprise demands for pentest reports in procurement
  • Simulates real-world SaaS risks: session hijacks, forgotten admin panels, and CI/CD misconfigurations

From Slack’s private GitHub leak to Okta’s support portal breach—SaaS is always in the spotlight.

Pentesting shows customers you take trust seriously —before they ask.

SaaS Platforms industry
Mobile & Desktop Applications
  • High-value targets for credential theft, code tampering, insecure data storage, and platform-specific bypasses
  • Threat actors exploit overlooked client-side flaws to gain access to sensitive data and user sessions
  • Pentesting identifies vulnerabilities that lead to fraud, reputational risk, and app store delisting

Business Value: Reduces breach risk in mobile channels, ensures platform compliance (App Store, Play Store),
and protects brand trust where most users engage.

Mobile & Desktop Applications industry
Web Applications & APIs
  • Core of digital business operations, frequently exposed to authentication flaws, API chaining abuse, and business logic manipulation
  • Pentesting simulates full attacker workflows across UI and API surfaces to reveal real-world exploitation paths
  • Focus on uncovering hidden vulnerabilities that impact revenue flow, user integrity, and data confidentiality

Business Value: Protects critical revenue-generating services, accelerates enterprise sales (SOC 2 / ISO 27001 alignment), and reduces incident response costs.

Web Applications & APIs industry
Cloud & Network Infrastructure
  • Prone to misconfigured access controls, exposed cloud assets, and lateral movement inside virtual networks
  • Attackers exploit these paths to access production data
    or disrupt services through privilege escalation
  • Pentesting validates cloud hardening efforts, helping prioritize high-impact misconfigurations and policy enforcement gaps

Business Value: Prevents costly outages and data leaks, validates ROI from cloud security tooling, and strengthens board-level trust in infrastructure governance.

Cloud & Network Infrastructure industry
Generative AI Applications & Agents
  • Exposed to prompt injection, tool misuse, training data leaks, and automated misuse scenarios
  • Pentesting uncovers logic and workflow manipulation
    that could lead to sensitive output leakage, compliance violations, or autonomous execution abuse
  • Targets both user-facing GenAI interfaces and backend
    AI agent ecosystems

Business Value: Ensures safe AI rollout at scale, enables regulatory alignment (AI Act, GDPR), and safeguards innovation pipelines against emerging AI-specific threats.

What We Pentest And Why

Mobile Application icon
Mobile Application
Mobile apps face threats like insecure storage, weak encryption, and API abuse. Penetration testing helps uncover these vulnerabilities, safeguarding user data and ensuring secure transactions on mobile platforms.
Web Application icon
Web Application
Web applications are vulnerable to SQL injection, XSS, authentication flaws, and business logic attacks. Penetration testing identifies these risks, ensuring data protection, secure user interactions, and compliance
with security standards.
API icon
API
APIs are prone to authentication bypass, injection attacks, and data exposure. Penetration testing validates API security, ensuring controlled data access, secure communication, and resilience against cyber threats.
Cloud & Network icon
Cloud & Network
Cloud and network environments can suffer from misconfigurations, unauthorized access, and lateral movement threats. Penetration testing strengthens security controls, preventing breaches and ensuring a robust infrastructure.
AI systems icon
AI systems
AI systems are vulnerable to adversarial attacks, data poisoning, and model inversion threats. Penetration testing secures AI models by detecting weaknesses, ensuring reliable
and trustworthy decision-making.
