Cybersecurity challenges for fintech

The fintech sector operates at the edge of innovation and risk. Strict regulatory requirements, millions of transactions, and handling of sensitive data make it an attractive target for hackers.
Cybersecurity for fintech is critically important: vulnerabilities or data breaches can lead to serious financial and reputational losses, and sometimes even to the shutdown of the entire business.

Security challenges of large fintech corporations

Complex infrastructure, numerous integrations, insider risks, and millions of users create a high level of threats and require constant monitoring.
Cybersecurity challenges for medium-sized businesses

The growing number of users increases hackers’ interest. Insufficient monitoring and vulnerable integrations with partners also pose significant security risks.
Threats for fintech startups and small companies

The lack of basic policies (access control, passwords, backups), configuration errors, vulnerable applications or APIs, and limited budgets make them especially vulnerable.

Our services for fintech companies

01.Penetration testing

A comprehensive cybersecurity assessment through safe simulation of hacker attacks to identify vulnerabilities in advance. This testing provides insight into the real state of your system’s protection and its compliance with international standards.

02.24/7 cybersecurity monitoring

Fintech companies often suffer from targeted attacks, making continuous SOC monitoring essential. Round-the-clock oversight and prompt incident response minimize the risk of service disruptions and protect customer data.

03.Code security audit

Mobile applications, online banking, and financial APIs must be secure from the inside out. Code review helps identify potential vulnerabilities before release, preventing attacks and reducing the costs of fixing issues.

04.Smart contract audit

For blockchain projects, the security of smart contracts is critical. Reviewing logic and identifying vulnerabilities in the code help prevent asset losses caused by errors or malicious exploits. Such an audit is essential before launching tokenization and financial solutions.

05.Reverse engineering

This service is relevant for analyzing suspicious software, third-party integrations, or malware. It helps to understand the nature of the threat, identify potential risks for fintech businesses, and is used in cases of fraudulent attacks or data breaches.

06.Treatment and Recovery

After incidents such as ransomware, DDoS attacks, or data breaches, it’s crucial to restore stability quickly. The remediation and recovery service acts as “insurance” for businesses, helping minimize losses. However, the best strategy is to prevent such situations in the first place.

Vulnerabilities we detect

Cyber threats for fintech companies

01.

Weak authentication and 2FA

Simple passwords, lack of multi-factor authentication, or its improper configuration open the door to account and service compromise.

02.

API vulnerabilities

Insufficient validation or authorization, and injection attacks (SQL/NoSQL, IDOR) allow attackers to access or manipulate data.

03.

Cloud configuration errors

Public storage, exposed databases, or misconfigured IAM policies can lead to leaks of sensitive information and compromise of access keys.

04.

Smart contract vulnerabilities

Errors in contract logic or weaknesses in cryptographic components create risks of asset loss, especially in crypto, DeFi, and tokenization sectors.

05.

Social engineering

Phishing, business email compromise, or vishing allow attackers to bypass technical defenses and gain access to accounts and internal systems.

06.

Improper access controls

Excessive user privileges, unclosed accounts of former employees, and weak privilege management create serious internal threats.
