Cybersecurity in the financial industry

With the advent of digitization, companies have more and more channels enabled on the network.
Companies in the financial sector, banks, finance companies, insurance companies, and cooperatives, among others, provide many services digitally; this is already a fundamental issue for this sector and rather compete by innovating with new and more digital services.

However, this poses a significant challenge for this sector, which has to do with the whole cybersecurity issue and permeates various organization and service infrastructure levels.


The number of channels and tools with which the financial sector provides services to its customers (external and internal) is evident: Apps, service portals, information sites, email services, VPN, teleworking, Etc. This reality increases the risk of attacks in a sector that has always been a "favorite" of hackers.

And it is in the financial sector where more and increasingly diverse categories of highly sensitive customer data are handled on a daily basis, concentrated in large volumes and distributed across multiple systems, channels, and digital touchpoints, making this information especially attractive for cybercriminals and critical to protect with robust, end‑to‑end security measures.

• Personal information, name, and contact information.
• Income, companies, profits.
• Taxes.
• Family data.
• Credit cards, bank accounts, and financial products.
• Important dates of receipt of payment.
• Authorized data.

The financial sector’s cybersecurity risks span a wide spectrum, from purely technical vulnerabilities to risks directly linked to human behavior and organizational culture. On the technical side, institutions must contend with complex, interconnected systems, legacy applications, cloud environments, and a growing number of external integrations, all of which expand the attack surface and increase the likelihood of security breaches if not properly managed. On the human side, everyday decisions made by employees, partners, and even customers—such as how they manage passwords, recognize phishing attempts, or handle sensitive data—can either strengthen or severely weaken an organization’s security posture.

Some key factors that reflect the interaction between these two dimensions include the robustness of infrastructure and network configurations, the frequency and quality of security testing, the effectiveness of identity and access management, the level of employee awareness and training around cyber threats, and the existence of clear, enforced policies for remote work and third‑party access. Together, these elements determine how resilient a financial institution will be in the face of increasingly sophisticated cyberattacks.

• Infrastructure is not tested regularly, proactively looking for vulnerabilities.
• Outdated system versions without the latest security updates applied.
• Unique accesses without proper management.
• Equipment connected to unsecured networks.
• Weak password and authentication policy in the organization.
• Access management must terminate (change of positions, personnel departures, temporary).
• Secure operation strategies for remote work.
• Guidelines for monitoring suspicious behavior.
• Employees are not informed of the security risks present.
  
  

As we can see, these aspects of cybersecurity involve the necessary and appropriate technological tools and the necessary processes to provide organizations with secure ways of operating that can be audited and constantly improved.


 What is secure today is no longer secure tomorrow. Just as we are advancing every day with more and better systems in organizations, hackers are also constantly "innovating" in the way they carry out their criminal activities to find new vulnerabilities.


The UN says, every 39 seconds, computer attacks are registered, figure increasing quantity and complexity.


Challenges are many, and the best initiative to manage this reality is not to take it lightly. The accelerated digitalization that we have experienced as a result of the pandemic is a factor that has played against us since "there was no time" to properly integrate the cybersecurity chapter within the various digital transformation initiatives of some companies.


So here are ten concrete actions that will help mitigate the risk of vulnerabilities:

1. Every digitization project must have the time and resources to assess cybersecurity.
   
   
2. Validate your security scheme systematically and periodically to improve your defenses constantly.
   
   
3. Review, strengthen and improve your authentication and permissions management policies.
   
   
4. Be clear about your software and hardware assets inventory to keep them up to date with the security patches constantly released by manufacturers.
   
   
5. Pay special attention to pieces of software that are obsolete or no longer have regular updates from the manufacturer.
   
   
6. Awareness and understanding of the problem are necessary at all levels of the organization, from management to operational staff; this will be the first line of defense before the bits and bytes.
   
   
7. The cybersecurity team must be actively involved in defining digitization, remote work, access, and data management processes. 
   
   
8. Use recognized platforms and services that provide objective support for your digitization applications, such as Adobe, AWS, Azure, and Cloudflare. 
   
   
9. Implement a regulatory compliance matrix, which allows a gradual but sustained implementation; we know that the task can be overwhelming and very demanding on resources. 
   
   
10. Processes are the key to having a 360-degree view of where we are and where we need to go with security procedures. Update and test them constantly; you will be surprised at the vulnerabilities you can discover.

In conclusion, cybersecurity is an increasingly crucial issue within financial organizations and has become even more relevant due to the accelerated digitalization and broader digital transformation processes of the last two years. The expansion of digital channels, remote work models, and cloud-based services has multiplied the number of potential entry points that attackers can exploit, turning cybersecurity from a purely IT concern into a strategic, board-level priority and an essential pillar of any serious  Digital Transformation agenda.

The defense factor is not only technical; it also involves robust processes, a solid organizational culture, and continuous awareness-building among people at every level of the company. Policies, controls, and technologies must be aligned with how teams actually work day to day, so that employees, suppliers, and partners understand that their actions—how they manage passwords, share information, or access systems—can represent critical vulnerabilities that hackers are ready to use. In this sense, a mature digital transformation program must explicitly integrate security by design, ensuring that every new digital capability, channel, or automation initiative is evaluated through a cybersecurity and data protection lens.

Addressing these challenges requires a comprehensive approach: clear governance, well-designed and regularly tested procedures, ongoing training, and the integration of security considerations into every digital initiative from the outset. Digital transformation in the financial sector cannot be considered complete if it does not embed cybersecurity into architectures, processes, and customer journeys, from core banking modernization to advanced analytics, open banking APIs, and omnichannel experiences. Financial institutions that treat cybersecurity as an intrinsic component of their operating model—and of their broader digital transformation roadmap, not as an isolated project—will be better positioned to protect their customers, comply with regulations, accelerate innovation, and sustain trust in an increasingly hostile digital environment.
