Identity has become the front door to everything your organisation relies on. Staff, partners, contractors and machines all need access to cloud apps, on-prem systems and data. Attackers know this, which is why phishing, credential theft and privilege abuse remain their favourite routes in. Building a robust security foundation therefore starts with identity security. In this blog, we look at the challenges organisations face, why identity security is so important, and how Integrity360 can help you put strong, sustainable controls in place.

The challenges organisations face

Most organisations now operate hybrid environments with a mix of cloud and on-premises systems. That creates identity sprawl. Human users, service accounts, bots and workloads each accumulate permissions across Microsoft 365, Azure, AWS, Google Cloud and dozens of SaaS tools. Keeping track of who has access to what quickly becomes difficult. The joiner, mover, leaver process often relies on manual steps, which means access is not removed promptly when people change roles or leave. Orphaned accounts and over-privileged users become common.

Password fatigue is another problem. Users juggle multiple identities and credentials, which encourages weak passwords and reuse. Even where multi-factor authentication exists, attackers increasingly exploit MFA fatigue or social engineering to bypass it. Privileged accounts present an even greater risk. Admin rights and standing privileges, left on by default, provide the keys to the kingdom. If an attacker compromises one of these identities, lateral movement and data exfiltration can follow.

Shadow IT complicates visibility further. Teams adopt new SaaS tools without central approval, creating unmanaged identities and access paths. Meanwhile, legacy systems and directories persist alongside modern identity platforms, making consistent policy enforcement a challenge. Compliance requirements add pressure, requiring demonstrable controls, audit trails and evidence of least privilege. Finally, many teams struggle with the skills and time needed to operate identity and access management technologies effectively day to day. All of this increases exposure and makes swift, confident decision-making harder during incidents.

Why identity security is the cornerstone of modern defence

Identity sits at the heart of Zero Trust. When networks are porous and devices are diverse, identity becomes the most reliable control point. Strong identity security reduces the likelihood of a breach by ensuring that only the right people and services get the right access at the right time. It limits the blast radius if an account is compromised and makes attacker movement more difficult and noisy.

The core principles are straightforward. Enforce strong authentication to verify users and systems. Apply least privilege so access aligns to role and business need. Replace standing admin rights with just-in-time and just-enough access. Continuously evaluate risk signals during sessions, such as location, device posture and behaviour, and adapt access accordingly. Monitor privileged activity closely and record high-risk sessions for accountability. Govern identities throughout their lifecycle so access is approved, reviewed and revoked in a timely way.

Done well, identity security delivers business benefits beyond risk reduction. Single sign-on and passwordless options improve user experience and productivity. Automated joiner, mover, leaver workflows reduce service desk load and tighten compliance. Consistent policies across cloud and on-prem systems make audits faster and less painful. Crucially, identity-centric controls integrate with your wider cyber security stack, enriching detection, speeding response and improving overall resilience.

Building blocks for a robust identity security foundation

Start with visibility. Discover every identity in your environment, human and non-human, and map their entitlements across directories, clouds and key applications. Identify stale, orphaned and highly privileged accounts. This sets a baseline and reveals quick wins.

Strengthen authentication. Roll out phishing-resistant MFA wherever possible and close legacy authentication gaps. Introduce single sign-on to centralise control and reduce password sprawl. For higher assurance, consider risk-based conditional access that adapts to signals like device health or unusual behaviour.

Tackle privilege. Implement privileged access management to vault credentials, broker sessions and remove standing admin rights. Use just-in-time elevation so powerful permissions exist only for the duration of a task, with approvals and full session recording where appropriate.

Govern access. Establish clear role-based access models and automate provisioning through identity governance and administration. Run regular access reviews with business owners, and embed joiner, mover, leaver workflows that remove access promptly. Extend governance to service accounts and machine identities, not just people.

Monitor and respond. Integrate identity signals with your security operations to detect suspicious logins, impossible travel, privilege escalations and dormant accounts coming back to life. Identity threat detection and response helps you spot and contain account-based attacks before they become full incidents.

Measure and improve. Track metrics such as MFA coverage, privileged account reduction, access review completion and time-to-deprovision. Use these to guide ongoing improvement and to demonstrate progress to stakeholders and auditors.
