Penetration Testing for the Banking Sector
Secure your banking systems and protect sensitive financial data from cyber threats. Pluto Cyber Security offers expert penetration testing to help banks stay ahead of hackers and maintain trust with their customers.
Overview
How We Secure Banking.
Protect your bank’s data and infrastructure from relentless cyberattacks with trusted security solutions.
Banks face constant cyber threats that target sensitive data and critical systems. Breaches can severely damage reputation and customer trust. Attackers use advanced methods, which makes strong defenses essential. Pluto Cyber Security’s expert team helps you find and fix weaknesses before criminals exploit them.
Proactive steps reduce risks and ensure compliance with banking regulations. Regular penetration testing keeps your security up to date and protects your bank from evolving cyberattacks.
Threat picture
How Banks Get Attacked.
Banks are tested more than almost any other sector, so the findings that remain are subtle. They are usually about authorisation, not authentication.
Authorisation between accounts and roles
Getting in is hard. Moving sideways once in is often much easier. Whether one customer can reach another's account data, or a support user can act beyond their remit, is the question that produces the most serious findings.
Payment and transfer logic
Limits that can be bypassed by splitting a transaction, approvals that can be replayed, and beneficiary changes that skip verification. These are logic flaws, which means a person has to look for them.
Open banking and API access
Third-party providers hold consented access to customer data and, in some cases, payment initiation. We test what a compromised or malicious provider could reach, and whether consent is enforced on every call rather than only at the start.
Internal tooling and support access
Back-office consoles see every account. They are built for staff, often under less scrutiny than the customer app, and an attacker who reaches one has reached everything behind it.
What we deliver
What Pluto Cyber Security Offers Banking Clients.
Penetration Testing
Our experts identify exploitable vulnerabilities in your banking systems caused by software flaws, misconfigurations, or human error. We provide clear, actionable remediation guidance along with full visibility into your security posture. This enables faster, informed decision-making and significantly reduces your risk of breach.
Mobile Application Testing
We identify security vulnerabilities in your mobile applications that could expose sensitive data or compromise transactions. Our testing ensures secure authentication, data protection, and resilience against real-world attack scenarios. You gain actionable insights to strengthen your apps, protect users, and maintain compliance with mobile security standards.
Firewall Security Assessment
We assess and validate your firewall configurations to identify misconfigurations, rule gaps, and potential exposure points. Our experts ensure proper segmentation, access control, and policy enforcement to prevent unauthorized access. You gain clear, actionable insights to strengthen your network defenses, reduce attack surface, and maintain a secure, resilient environment.
Phishing Assessment
We simulate real-world phishing attacks to evaluate your organization’s exposure to social engineering threats. Our assessments identify user susceptibility, email security gaps, and response weaknesses. You gain actionable insights and targeted training to strengthen awareness, reduce risk, and build a more resilient human defense layer.
Cloud Security Solutions
We secure your cloud environments by identifying misconfigurations, excessive permissions, and exposed assets across platforms like AWS, Azure, and Google Cloud. Our assessments ensure proper access controls, data protection, and secure architecture. You gain clear visibility into risks and actionable steps to prevent breaches and maintain a resilient cloud infrastructure.
Compliance
What Banks Have to Answer To.
PRA and FCA expectations around operational resilience require you to understand your important business services and demonstrate you can stay within impact tolerances. Testing evidence is part of showing that rather than asserting it.
CBEST applies to firms whose failure would affect financial stability, and it is intelligence-led red teaming rather than a penetration test. Clearing conventional findings first is considerably cheaper than discovering them during a CBEST exercise.
PCI DSS applies to card systems, and UK GDPR to customer data throughout. Our reporting maps each finding to the frameworks it touches so one engagement feeds several reporting lines rather than generating several separate pieces of work.
- PCI DSS
- SOC 2
- ISO 27001
We test banking and payment platforms, customer portals and the APIs behind them. Engagements are run by senior testers, under NDA, with evidence handling and retention agreed in writing before work starts, which is normally what your third-party risk team needs to see.
