Who is Responsible for Information Security?

Information security, or infosec, is not just a concern for IT departments or cybersecurity professionals – it's a collective responsibility that permeates every level of an organisation. From top management to frontline employees, everyone has a role to play in protecting sensitive data and mitigating risks. As companies grapple with evolving threats and increasingly complex regulatory requirements, understanding the distribution of accountability is crucial.

With that in mind, we’ll explore some key stakeholders who must take responsibility for information security.

Executive Leadership

Top-level executives, including CEOs and board members, are ultimately accountable for establishing a culture of security within an organisation. They set the tone from the top, allocate resources for cybersecurity initiatives, and make strategic decisions regarding risk management. 

However, sometimes cybersecurity is not taken as seriously at board level as security professionals would like. In our latest report on trends in information security, 30% of security leaders agreed that it would take until after becoming a victim of an attack for board members to want to gain expertise in cybersecurity – at the cost of potential financial penalties and reputational damage.

By prioritising information security at the highest level, executives can demonstrate the importance of protecting sensitive data and ensure that security measures align with business objectives. 

IT Departments

IT departments serve as the frontline defenders against cyber threats, responsible for implementing and managing security controls, monitoring network activity, and responding to incidents. They oversee the deployment of firewalls, antivirus software, encryption protocols, and other technical safeguards to safeguard data assets.

Additionally, IT professionals play a critical role in educating employees about cybersecurity best practices and enforcing compliance with security policies and procedures.


Every employee within an organisation shares responsibility for maintaining information security. Whether it's safeguarding login credentials, recognising phishing attempts, or adhering to data protection protocols, employee awareness and vigilance are essential components of a robust security posture. 

Training programmes and awareness campaigns can empower employees to recognise potential threats and adopt secure behaviours, helping reduce the risk of human error and insider threats.


Third-Party Vendors

In today's business world, many organisations rely on third-party vendors and service providers to support their operations. However, outsourcing certain functions can introduce additional security risks, particularly if vendors have access to sensitive data or systems. 

Companies must carefully vet and manage their vendor relationships, ensuring that vendors adhere to stringent security standards and contractual obligations. By holding vendors accountable for maintaining information security, we can reduce the risk of data breaches and supply chain attacks.

Regulatory and Compliance Bodies

Regulatory compliance is a driving force behind many information security initiatives, as organisations must adhere to a complex set of laws, regulations, and industry standards. Regulations, such as GDPR, the EU Cybersecurity Act and SOX, impose requirements for protecting personal data, financial information, and other sensitive assets. 

Compliance with these regulations not only helps organisations avoid legal penalties but also enhances trust and credibility among customers and stakeholders. Regulatory compliance should be viewed as a shared responsibility, with companies proactively addressing requirements through effective governance and risk management practices.

By recognising and embracing their collective responsibility for safeguarding sensitive information, individuals, organisations and regulatory bodies can effectively mitigate cyber risks and uphold the trust and integrity of their operations.
