Does an organisation need a CISO in the face of cyber attacks?

With cyberattacks becoming increasingly prevalent, organizations face the question not of if they'll be targeted, but when. This shifting landscape has elevated the importance of the Chief Information Security Officer (CISO) role. However, the question remains: does every company truly need to invest in such a specialized position?

The evolution and role of the CISO

A CISO serves as a senior executive responsible for developing and implementing comprehensive information security programs that safeguard an organization's data and systems. This position is relatively new in the corporate landscape—Citigroup pioneered it around 1994 in response to emerging digital threats.

At its core, the CISO's primary responsibility involves protecting information assets from both internal and external threats. This executive coordinates security teams, monitors potential vulnerabilities, and develops risk mitigation strategies tailored to the organization's specific needs.

Core responsibilities of an effective CISO

Today's CISO handles a broad spectrum of critical tasks:

• Developing and implementing robust security policies

• Managing information security personnel

• Conducting continuous network monitoring to detect suspicious activities

• Overseeing incident response processes

• Creating system recovery strategies for potential failures

• Ensuring compliance with industry regulations and standards

• Facilitating communication between technical and non-technical teams

• Managing crisis situations during security incidents

It's worth emphasizing that an effective CISO requires both extensive technical expertise and business acumen—only this combination of skills can provide genuine organizational protection.

Three distinct CISO profiles

In practice, CISO specialists typically fall into three main categories:

TISO (Technical Information Security Officer) specialists concentrate primarily on technical security controls and solving specific technological challenges.

BISO (Business Information Security Officer) professionals focus mainly on data security issues that directly impact business operations.

SISO (Strategic Information Security Officer) experts ensure alignment between long-term business goals and security team initiatives.

The appropriate profile selection should reflect the organization's specific characteristics and cybersecurity priorities.

Changing organizational positioning of CISOs

Traditionally, CISOs worked closely with other executives such as the Chief Information Officer (CIO) or Chief Technology Officer (CTO). However, recent years have witnessed a significant shift in reporting structures.

Research shows that 61% of CISOs no longer report to the CIO as was previously standard practice. Instead, they increasingly report directly to the CTO, Chief Operating Officer (COO), or even directly to the Chief Executive Officer (CEO). This transformation reflects cybersecurity's growing recognition as a strategic business element rather than merely a technical consideration.

Modern challenges facing CISOs

Today's CISOs contend with numerous complex challenges:

• Keeping pace with rapidly evolving cyber threats

• Managing increasingly complex IT infrastructures

• Maximizing often insufficient security budgets

• Convincing leadership teams of cybersecurity's strategic importance

• Addressing the shortage of qualified security professionals

• Mitigating supply chain risks

Perhaps most challenging is incident response time management. According to IBM research, the optimal timeframe for identifying, intercepting, and countering security breaches ranges from 150 to 287 days, depending on the organization's specific characteristics. Following incident detection, containment and resolution should ideally occur within one to three months.

The financial investment in a CISO

Bringing a CISO on board represents a significant financial commitment. According to Glassdoor data from January 2024, the median annual compensation for this position stands at approximately $386,000, with some roles commanding up to $585,000.

In the banking and financial services sector, CISO salaries typically range from $180,000 to $400,000 annually. These substantial figures reflect the position's critical importance, particularly in sectors handling sensitive data.

Which organizations truly need a dedicated CISO?

The answer to our central question depends on several key factors. Large enterprises with extensive IT infrastructure and numerous potential attack vectors unquestionably benefit from a dedicated CISO. Similarly, companies in high-risk sectors such as finance, healthcare, or energy—where security breaches could have devastating consequences—should prioritize this position.

Organizations that process substantial volumes of personal data or other sensitive information face increased attack risks, further justifying a CISO's presence. Additionally, regulatory requirements play a crucial role—certain industries must employ dedicated information security leadership to maintain compliance.

For smaller organizations unable to sustain a full-time CISO, several alternatives exist. These include engaging a "virtual CISO" (as an external service), distributing CISO responsibilities among existing team members, or outsourcing security functions to specialized providers.

Building a comprehensive security culture

Regardless of whether an organization employs a dedicated CISO or opts for alternative solutions, developing a robust security culture among all employees remains paramount. Research consistently confirms that human factors continue to represent one of the weakest links in the cybersecurity chain.

A CISO plays a vital role in cultivating this culture through:

• Implementing effective training and awareness programs

• Establishing and enforcing comprehensive security policies

• Conducting regular penetration testing and attack simulations

• Championing "security by design" principles in new initiatives

• 
  

This last approach integrates security considerations from the earliest design stages, enabling early vulnerability detection and remediation before implementation.

Conclusion

As cyberattacks grow increasingly sophisticated, the CISO role becomes ever more crucial to organizational survival. While not every company requires a full-time specialist in this position, every organization should maintain a clearly defined information security management strategy.

Ultimately, the fundamental question isn't "Can we afford a CISO?" but rather "Can we afford the consequences of inadequate security management?" Considering that the average data breach now costs millions, investing in a competent CISO often represents the most effective protection for an organization's digital assets.
