Threat‑driven penetration testing for financial organizations

Simulate real-world threats on your apps, dApps, crypto wallets, and on-chain finance applications. Verify your capabilities, uncover vulnerabilities, and strengthen your systems and processes.

Trusted by the largest organizations

End-to-end assurance: Code, controls, compliance

Cyfrin penetration testing employs adversarial techniques to identify vulnerabilities across your web applications, APIs, infrastructure, and crypto-native components, including wallets, bridges, and decentralized applications (dApps).

Safely simulate real world attacks

Break your systems in a controlled environment before attackers do it in production.

Threat model analysis

Harden your perimeter and pipelines. Cyfrin’s team mimics real threat actors in a white hat environment, helping your team identify, reproduce, and remediate weaknesses before they can be weaponized. 

Real-world scenarios and prioritized remediation

Realistic threat models, not just checklists. Prioritized remediation plans with clear fixes. 

Cross-domain expertise

Benefit from our extensive experience in traditional development environments and blockchain attack surfaces. 

Test suite creation & enhancement

Enhance regression safety with fuzzers and additional test cases that catch edge case behaviors.

Post-deployment monitoring

Continuous engagement options for evolving attack surfaces. Strengthen trust with users, partners, and regulators.

What is penetration testing?

Penetration tests, also known as “pentests,” are a controlled, simulated attack on your system to reveal potential flaws, weaknesses, or vulnerabilities. They’re generally executed by contracted, ethical hacking teams outside your organization who can review your systems without bias or knowledge of their development to optimize the results. Cyfrin’s blockchain pentest services are performed by our in-house team of security researchers or select external contractors. 

1
Setup timelines and onboarding
Our engineers will estimate the timeline based on codebase complexity and size and open a line of communication.
2
Discovery and reconnaissance
Cyfrin researchers will research your systems, protocols, or smart contracts to understand their flows, functions, and potential gaps. 
3
Scanning
Following the initial research phase, security researchers will use a variety of technical tools to scan for openings to exploit including static and dynamic analysis. 
4
Gaining and maintaining access
Using intelligence gathered, the team will attempt to exploit your web, blockchain infrastructure, or wallet to deploy some payload. The team will continue to probe exploits and maintain access to simulate persistent threats while also searching for additional opportunities. 
5
Reporting, remediation, and re-testing
When the pentest exercise is fully complete, Cyfrin’s researchers will prepare and deliver a report of all findings, gaps, and vulnerabilities along with recommended remediations. When remediations are complete, our team will start the process again to verify all identified vulnerabilities are fixed.
