The cybersecurity challenge in the financial sector
Digital transformation has revolutionized the financial market. Open Finance, Pix (Brazil’s instant payment system), mobile banking, open APIs, integrations with fintechs and multi-cloud environments have increased efficiency and improved the customer experience. At the same time, this evolution has significantly expanded the attack surface of financial institutions. Today, banks, fintechs, insurers and credit unions operate in highly connected, regulated and transactional environments, where:
- Thousands of transactions take place every second
- Sensitive and financial data is processed continuously
- System unavailability directly affects customers and the market
- Trust is a strategic asset
In this context, a cyber incident can cause
- Institution
- Disruption of banking services and payment methods
- Financial fraud and direct losses
- Customers
- Sensitive data leakage
- Regulator
- Regulatory fines
- Market
- Severe reputational damage
- Systemic impacts on the market
The financial sector as a strategic target for cybercrime
Financial institutions concentrate high-value digital assets: personal data, financial histories, credentials, transactions and liquidity. They also operate under strong pressure for 24x7 availability. This combination creates an attractive environment for attackers who exploit:
Point of entry
- Targeted social engineering
- Phishing and Business Email Compromise (BEC)
- Attacks on third parties and critical suppliers
- Exploitation of vulnerabilities in web applications and APIs
Lateral movement
To reach the transactional systems
Transactional systems
Data, credentials, transactions and liquidity
The sector’s operational urgency makes extortion attacks particularly critical, since shutdowns can affect thousands, or millions, of customers at the same time.
That is why the financial sector requires advanced prevention, detection and response strategies, aligned with the criticality of the business.
Regulatory context and compliance in the financial sector
The Brazilian financial environment is highly regulated. Cybersecurity is directly linked to compliance with standards and requirements such as:
- LGPD General Data Protection Law
- BACEN Resolutions of the Central Bank of Brazil
- CMN Rules of the National Monetary Council
- Payment institutions Security requirements
- Open Finance Security and API requirements
- PCI DSS Card environments
- ISO/IEC 27001 And international best practices
Beyond technological protection, institutions need to demonstrate governance, risk management, business continuity and robust internal controls. In this context, cybersecurity is a regulatory requirement, a factor of market trust and a competitive differentiator.
How to protect the financial sector?
Here is a look at our approach:
Identify
Journey: IdentifyVisibility and inventory of critical assets
Complete mapping of transactional systems, APIs, applications, integrations with fintechs, and on-premises and cloud environments.
Continuous vulnerability management

More than responding to incidents, we help financial organizations evolve their cybersecurity maturity. Get in touch with us and strengthen your institution’s cybersecurity.
Frequently asked questions
Which regulations apply to cybersecurity in the financial sector?
The main ones are Brazil’s LGPD (General Data Protection Law), the resolutions of the Central Bank of Brazil (BACEN) and the rules of the National Monetary Council (CMN), the security requirements for payment institutions and for Open Finance, PCI DSS for card environments and ISO/IEC 27001. Beyond technological protection, institutions need to demonstrate governance, risk management, business continuity and internal controls.
Which attacks most often target financial institutions?
Targeted social engineering, phishing and Business Email Compromise (BEC), attacks on third parties and critical suppliers and exploitation of vulnerabilities in web applications and APIs, as a point of entry for lateral movement to the transactional systems. With the pressure for 24x7 availability, extortion is particularly critical: a shutdown can affect thousands, or millions, of customers at the same time.
How do you protect APIs and Open Finance?
By mapping transactional systems, APIs and integrations with fintechs, protecting open integrations, monitoring calls, using strong authentication and mitigating API attacks. In practice, this includes API discovery and inventory, OWASP API Security Top 10 testing, rate limiting and runtime protection against attacks such as BOLA, BFLA and Mass Assignment, as well as penetration testing of web applications and APIs.
How do you detect attacks that use legitimate credentials?
With behavioral analytics (UEBA), one of the detection layers of the Cyber Defense Center, the Vortex Converged NG-SOC (NG-SOC Convergente). The platform builds baselines of the normal behavior of users, devices and services and flags deviations such as atypical access, lateral movement, anomalous use of credentials, data exfiltration and abuse of privileged accounts. It is especially effective against insider threats and attacks with legitimate credentials, scenarios in which controls based solely on signatures or rules are blind.
How does Vortex help fight digital fraud?
Inside the environment, the behavioral analytics (UEBA) of the Cyber Defense Center flags anomalous use of credentials and abuse of privileged accounts. Outside it, the Threat Intelligence of Vortex Cockpit monitors leaked credentials, fake websites, profiles and apps, secrets exposed in public repositories and fraud offers against the brand, with a takedown queue.
How do you assess the risk of third parties and critical suppliers?
From the outside, without touching the supplier. In Vortex Cockpit, each critical supplier receives a grade from A to E calculated only from public sources and DNS, based on what can be seen from the outside, such as email, certificates, services and leaks. Vortex also offers Third-Party Risk Management consulting.
How do you demonstrate security governance to the board and auditors?
Vortex Cockpit has views for the Board and the CEO, with adherence to the approved risk appetite and the decisions that depend on senior management, and for the CISO and GRC, with remediation deadlines, accepted risks, compliance and audits. The Vortex Score measures posture by the functions of NIST CSF 2.0, with the rigor audits require. Vortex service management completes this with an executive presentation, monthly reports on vulnerabilities, compliance, detection and response and SLA, and an incident report with the root cause.
How does Vortex ensure uninterrupted 24x7 monitoring?
The Cyber Defense Center operates from two active centers of equal size, in Rio de Janeiro and São Paulo, with no primary and contingency site: if one fails, the other takes over the entire operation. The infrastructure is replicated in data centers in Brazil and the US, with redundant internet links. Vortex is also ISO 22301 certified, for business continuity.
What certifications and recognition does Vortex have?
Vortex is certified to ISO/IEC 27001 and ISO/IEC 27701, for information security and privacy, which cover its own processes and the handling of client information, and to ISO 22301, for business continuity. It is also a Leader in the ISG Provider Lens 2026 for Next-Gen SOC/MDR Services (Midmarket) in Brazil.
Does Vortex serve financial institutions?
Yes. Banco Arbi, IRB(Re), Petros and Austral are among the financial institutions that trust Vortex. Vortex protects the sector with the Cyber Defense Center, the NG-SOC Convergente, with 24x7x365 detection and response from two active centers, in Rio de Janeiro and São Paulo. It is a Leader in the ISG Provider Lens 2026 for Next-Gen SOC/MDR Services (Midmarket) in Brazil.
