The New
Cybersecurity
Landscape
AI is changing the speed and scale of cyber threats. Identity, resilience, cloud security and post-quantum preparation are becoming central to how organisations protect digital systems.
Cybersecurity is no longer simply about protecting a company's network perimeter. Modern organisations depend on cloud platforms, connected devices, software suppliers, digital identities and increasingly AI-powered systems.
That means security teams are being asked to do more than block attacks. They must understand what they have, control who can access it, detect suspicious activity, respond quickly and recover when something goes wrong.
In focus
2026 signalsAI-powered attacks
Artificial intelligence can make phishing, fraud and social engineering more convincing and scalable.
Identity becomes the perimeter
Strong authentication and carefully managed access are increasingly central to security.
Resilience matters
Prevention is only part of the job. Organisations also need reliable response and recovery plans.
Quantum preparation
The transition toward post-quantum cryptography is becoming a long-term security planning issue.
What is changing in cybersecurity in 2026?
The biggest shift is not one new type of malware. It is the growing complexity of the digital environment organisations must defend.
Employees work from multiple locations. Applications run across cloud environments. Companies depend on external software and service providers. Artificial intelligence is being integrated into everyday workflows. Meanwhile, attackers continue to target credentials, data, vulnerabilities and human trust.
Security therefore has to become a continuous process rather than a single product or one-time project.
Threats shaping 2026
What to watchCredential and account attacks
Compromised passwords, stolen sessions and poorly protected accounts can provide a path into otherwise well-defended environments.
AI-enabled social engineering
AI can help create more convincing messages, impersonation attempts and fraudulent content, increasing pressure on human verification.
Ransomware and data theft
Organisations continue to face risks from disruption, data exposure and extortion, making recovery planning essential.
Cloud and SaaS risk
Misconfiguration, excessive permissions and vulnerable services can create security gaps across distributed infrastructure.
Third-party compromise
A security problem at a supplier or software provider can become a security problem for many organisations at once.
Data exposure
Sensitive information can be placed at risk through weak access controls, vulnerable systems or accidental disclosure.
The six functions of cybersecurity
NIST CSF 2.0Govern
Establish cybersecurity strategy, responsibilities, policies, risk tolerance and oversight.
Identify
Understand assets, systems, data, suppliers and the risks that matter most to the organisation.
Protect
Put safeguards around identities, systems, software, data and technology infrastructure.
Detect
Find suspicious activity and security events quickly enough to limit their potential impact.
Respond
Coordinate actions during an incident, communicate clearly and contain the consequences.
Recover
Restore affected services, learn from incidents and improve resilience for the future.
Organisations need to understand which AI services employees and systems are using and what information those services can access.
Sensitive information should be handled carefully when AI tools are used for analysis, automation or content generation.
Models, datasets, APIs and third-party AI services introduce additional dependencies that need risk management.
As synthetic text, audio and images become easier to produce, people may need stronger processes for verifying important requests.
Preparing for the post-quantum era
Quantum computers powerful enough to threaten some current cryptographic systems are not a routine reality today. But changing cryptography across large technology estates can take years.
NIST has already finalised three post-quantum cryptography standards and recommends that organisations begin the transition process.
Cryptography migration is becoming a planning issue.
The challenge is understanding where vulnerable cryptographic algorithms are being used and planning future replacements.
Cybersecurity checklist
Practical basicsFor individuals
- Use strong, unique passwords
- Turn on multi-factor authentication
- Keep operating systems and apps updated
- Be cautious with unexpected messages and links
- Review account recovery options
- Keep important data backed up
For organisations
- Maintain an accurate asset inventory
- Strengthen identity and access controls
- Prioritise security updates and vulnerabilities
- Monitor important systems and accounts
- Maintain an incident response plan
- Test backups and recovery procedures

Strategic viewWhat comes next?
2027 → 2030AI agents and security
As software agents gain the ability to perform more tasks, organisations will need to control their identities, permissions and actions.
Cryptography migration
Post-quantum standards are likely to become a larger part of long-term technology modernisation plans.
Security beyond prevention
Organisations will increasingly measure how quickly they can detect, contain and recover from incidents.
