Cybersecurity in the financial industry

Cybersecurity in the financial industry is the set of processes, technologies and habits that protect customer data, transactions and trust across every digital channel. It is no longer an IT concern. It determines whether a bank, insurer or cooperative can innovate, comply with regulators and keep customers who expect their money and identity to be safe.

Picture the executive committee of a regional bank on the Monday after a phishing campaign reached its staff. No funds were lost. A handful of employees clicked, one set of credentials was used for a few hours, and the security team contained it. Yet the discussion in the room is uncomfortable. The chief digital officer wants to launch a new onboarding journey next month. The chief risk officer asks whether the controls around third-party access are ready. The chief executive wants to know how the bank would have explained the incident to customers if it had been worse. The question underneath is whether the speed of digitization has outrun the speed of protection.

With the advent of digitization, companies have more and more channels enabled on the network. Companies in the financial sector, including banks, finance companies, insurers and cooperatives, provide many services digitally, and compete by innovating with new, more digital offerings. This poses a significant challenge, because cybersecurity permeates every level of the organization and its service infrastructure. It is a sector that has always been a favorite of attackers, and its attack surface grows with each new app, portal and integration.

Why is the financial sector such an attractive target?

The number of channels and tools through which the financial sector serves its customers, both external and internal, is evident: apps, service portals, information sites, email services, VPNs and teleworking, among others. Each is a potential entry point. Beyond the number of doors, there is the value of what lies behind them. The financial sector handles, on a daily basis, a larger and more diverse range of highly sensitive customer data, concentrated in large volumes and distributed across multiple systems, channels and digital touchpoints. That concentration makes the information especially attractive to cybercriminals and critical to protect with robust, end-to-end security measures.

Think about what a single customer file can contain. It includes personal information, name and contact details, along with income, companies and profits. It holds tax information and family data, credit cards, bank accounts and financial products, and the important dates on which payments are received. It also includes the data customers have authorized the institution to use. Assembled together, this is enough to impersonate a customer convincingly, which is why fraud that begins with a data breach often continues for months.

The cost of failure is measurable. IBM's analysis of the financial industry in its 2024 Cost of a Data Breach research puts the average cost of a breach for financial firms at 6.08 million US dollars, 22 percent above the global average of 4.88 million, and attributes 51 percent of breaches in the sector to malicious attacks, as summarized in IBM's report on the cost of a data breach in the financial industry. The same analysis reports that human error accounted for 24 percent. The figure matters to a board because it combines direct costs with the harder-to-measure loss of customer confidence.

Where do the risks come from, technology or people?

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 raise the likelihood of a breach if they are 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 strengthen or severely weaken the security posture.

Some factors reflect the interaction between the two dimensions. They 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, and the existence of clear, enforced policies for remote work and third-party access. Together these elements determine how resilient an institution will be against increasingly sophisticated attacks.

In practice, the weaknesses that recur are quite ordinary. Infrastructure is not tested regularly to look proactively for vulnerabilities. Systems run outdated versions without the latest security updates. Unique accesses are not properly managed, and access that should end with a change of position, a departure or a temporary assignment is left active. Equipment connects to unsecured networks. Password and authentication policies are weak. Remote work lacks secure operating strategies, there are no guidelines for monitoring suspicious behavior, and employees are not informed of the risks that exist. None of these requires a sophisticated adversary. They require only the time and patience that attackers have.

These aspects of cybersecurity involve the necessary technological tools and the processes that give organizations secure ways of operating that can be audited and constantly improved. What is secure today is no longer secure tomorrow. Just as organizations advance with better systems, attackers innovate in their methods to find new vulnerabilities. According to figures attributed to the United Nations, a computer attack is registered every 39 seconds, and the number is rising in both quantity and complexity. Whatever the exact interval, the practical implication is that defense must be continuous.

What did accelerated digitization change?

The acceleration of digital services in recent years, driven first by the pandemic and then by customer expectations that did not return to earlier levels, worked against security in one specific way. There was no time to properly integrate the cybersecurity chapter into the digital transformation initiatives of many companies. Remote work, cloud services and new channels were launched under deadline pressure, and controls were added afterwards, when they were added at all.

The result is a portfolio in which some of the most modern customer experiences sit on top of controls designed for an earlier era. Imagine a credit union that launched a mobile app in a matter of months. The app is well designed, but the identity checks for password resets were configured for speed and have never been reviewed. Or imagine an insurer that opened a broker portal to hundreds of intermediaries, without a routine for removing access when an agency changes staff. In both cases the digital initiative was a business success and the security debt grew silently behind it.

Understanding when the pressure to modernize becomes a risk is part of the planning discipline described in When is it necessary to implement a Digital Transformation?. The principle is to treat security as a design requirement rather than as a final gate.

A further consequence concerns suppliers. Modern financial institutions rarely run alone. They rely on cloud providers, payment processors, fintech partners, call centers and software vendors, and each connection extends the perimeter that must be defended. A weak control at a small partner can expose the institution as surely as a flaw in its own systems. For that reason, mature organizations extend their security expectations through contracts, require evidence of controls from critical suppliers and rehearse what happens when a partner is compromised. They also agree in advance who speaks to customers and regulators, because the quality of communication in the first hours often shapes how an incident is remembered.

What does a mature financial institution do differently?

Challenges are many, and the best initiative to manage this reality is not to take it lightly. Ten concrete actions help mitigate the risk, and they fall into three groups, covering how security is built into projects, how it is run day to day, and how the organization behaves.

In building, every digitization project needs the time and resources to assess cybersecurity, and the cybersecurity team must be actively involved in defining digitization, remote work, access and data management processes. The security scheme should be validated systematically and periodically, so that defenses improve constantly. Where the institution relies on platforms to support its digital applications, it makes sense to use recognized platforms and services that provide objective support, such as Adobe, AWS, Azure and Cloudflare. The same logic applies to the interfaces that connect the institution to partners, such as the open banking APIs that are now a regulatory and competitive reality.

In running, institutions should review, strengthen and improve their authentication and permissions policies. They need a clear inventory of software and hardware assets so that these can be kept current with the security patches that manufacturers constantly release, and they should pay special attention to software that is obsolete or no longer receives regular updates. A regulatory compliance matrix allows a gradual but sustained implementation, which is valuable because the task can be overwhelming and demanding of resources. Processes are the key to a 360-degree view of where the institution stands and where it needs to go. Updating and testing them constantly tends to surprise teams with the vulnerabilities it reveals.

In behavior, awareness and understanding of the problem are necessary at all levels, from management to operational staff, and they form the first line of defense before the bits and bytes. This is where culture matters. An employee who reports a suspicious email quickly, without fear of blame, is worth more than another tool. The lesson is consistent with the governance emphasis of the NIST Cybersecurity Framework 2.0, which adds Govern as a sixth function alongside Identify, Protect, Detect, Respond and Recover, as explained in NIST's note on the framework's expanded scope. Security, in other words, is a matter for the board and the executive team before it is a matter for the security operations center.

What this means for the C-level

For the chief executive, the key decision is to make cybersecurity part of the transformation roadmap rather than a parallel project. That means asking, at every major launch, what the security review found and what risk the institution has accepted. The leader who can answer those questions is the one who will speak with confidence to regulators, customers and the board after an incident.

For the chief risk and compliance officers, the priority is to translate the regulatory landscape into a matrix that the business can act on, with named owners and deadlines. For the chief commercial and customer officers, trust is itself a commercial asset. Customers who feel safe use more channels, hold more products and stay longer, so protecting them supports conversion and retention directly. Clear, honest communication about security measures, including fraud alerts and simple controls that customers can use, reinforces loyalty. For the chief financial officer, the arithmetic of prevention is favorable when set against the average cost of a breach, and efficiency comes from consolidating tools and automating routine controls.

For the chief operating and technology officers, the task is to align policies, controls and technologies with how teams actually work, so that employees, suppliers and partners understand that their actions, such as how they manage passwords, share information or access systems, can become critical vulnerabilities. A mature transformation program explicitly integrates security by design, so that every new capability, channel or automation is evaluated through a cybersecurity and data protection lens.

How to start next Monday

An experienced consultant would suggest three moves that cost little and reveal a great deal. First, ask the security team for a list of every person and organization with access to customer data, including suppliers and former employees, and have a business owner confirm that each access is still needed. Second, take the three most recent digital launches and ask when they were last tested for vulnerabilities and who accepted the residual risk. Third, run a short exercise with the executive committee in which a plausible incident is described and each member explains what they would do in the first hour, including how customers would be informed.

The results will show where processes are unclear, where ownership is missing and where investment is needed. Treat the exercise as the beginning of a cycle rather than a one-time audit, with findings assigned to owners, dates agreed and progress reported to the executive committee every quarter. Over time, the institution builds a record of risks reduced rather than reports filed, which is the evidence regulators, auditors and boards increasingly expect to see. 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 and omnichannel experiences. Institutions that treat cybersecurity as an intrinsic part of their operating model and of their roadmap will be better positioned to protect customers, comply with regulations, accelerate innovation and sustain trust in a hostile digital environment.

Frequently asked questions

Why are financial institutions targeted so often?

They hold concentrated, high-value data and process money directly, so a successful attack can be monetized quickly. They also run many channels and integrations with third parties, which widens the attack surface. Attackers need only one weak point, while the institution must protect all of them.

Is cybersecurity mainly a technology problem?

No. Technology is essential, but breaches frequently exploit people and processes, such as weak authentication, access that is never revoked or employees who are not trained to recognize phishing. IBM attributes a meaningful share of financial-sector breaches to human error. Effective programs combine controls, governance and culture.

What is the first step toward better security in a digital project?

Give every digitization project time and budget for a security assessment, and involve the cybersecurity team when processes, remote work, access and data management are defined. Early involvement is far cheaper than retrofitting controls after launch, and it avoids delays caused by late findings.

How often should security controls be tested?

Regularly and after significant changes, not only once a year. Test infrastructure for vulnerabilities, review access periodically, update the asset inventory and rehearse incident response. Because what is secure today may not be secure tomorrow, testing should be a continuous cycle with owners and deadlines.
