Adoption of new technologies can alter an organisation’s attack surface, requiring security controls, testing, and risk management to change.

Background for this topic.
Adoption is the extent to which people and organizations begin using a security technology, control, policy, or practice and incorporate it into routine work. In cybersecurity, adoption is more than purchasing or deploying a capability: it includes correct configuration, user participation, and continued use. Examples include enabling multifactor authentication, applying security patches, using secure coding practices, and collecting logs from systems that require monitoring.
Adoption matters because uneven or incomplete use leaves exploitable gaps. A partially deployed authentication control may protect some accounts while others remain exposed; delayed patch adoption can leave known vulnerabilities available to attackers; and missing or poorly configured logging can limit detection and investigation. Practitioners therefore assess coverage, exceptions, configuration quality, and whether controls operate as intended. Training, usable workflows, staged rollout, and measured policy compliance can improve adoption without encouraging insecure workarounds or unnecessary collection of personal data.

Cisco Cybersecurity Readiness Index Shows Only 3% of Companies Are Cyber ResilientCisco's 2024 Cybersecurity Readiness Index showed a concerning gap - while 80% of organizations felt confident in their cybersecurity readiness, only 3% had a "Mature" level of readiness. This suggests companies must plan cybersecurity budgets, upgrade infrastructure and adopt AI for resilience.
It comes as no surprise that today's cyber threats are orders of magnitude more complex than those of the past. And the ever-evolving tactics that attackers use demand the adoption of better, more holistic and consolidated ways to meet this non-stop challenge. Security teams constantly look for ways to reduce risk while improving security posture, but many
