In the modern cloud and hybrid enterprise, identity governance has evolved from an IT function to a core pillar of cybersecurity strategy. As workloads shift to distributed architectures, the number of identities, both human and non-human is exploding, creating a wider and more complex attack surface. In conversation with Bradley, VP and CISO at Paychex, we explored the urgent need for unified governance, the pitfalls of legacy systems, and practical steps to modernize identity security at scale.

Why Identity Security Now Goes Beyond Humans

Traditional identity security was once centered on usernames, passwords, and access rights for employees. Today, Non-Human Identities (NHIs)—including service accounts, bots, and machine credentials outnumber human identities in most organizations. Left unmanaged, NHIs create massive security blind spots, opening the door to excessive privilege, credential misuse, and stealthy lateral movement.

The Risks of Fragmented Governance

Organizations lacking a unified governance model face:

• Higher Breach Probability – Orphaned accounts and excessive privileges enable unauthorized access.

• Operational Disruption – Misconfigured permissions lead to downtime and outages.

• Increased Overhead – Managing identities in silos inflates costs and hinders automation.

As Bradley warns, “You can’t govern only part of your identities and expect positive outcomes, governance must be comprehensive.”

Modernizing Governance for Cloud & Hybrid

Legacy Identity Governance and Administration (IGA) tools struggle to manage NHIs and scale with cloud-native workloads. Bradley recommends replacing or augmenting them with cloud-native governance platforms that:

• Provide full visibility across human and non-human identities.

• Automate provisioning, deprovisioning, and entitlement reviews.

• Support Zero Trust principles and least privilege access models.

Best Practices for Scaling Identity Security

1. Visibility First – Inventory every identity across on-prem, cloud, and SaaS environments, identifying ownership, risk, and unused accounts.

2. Automate Lifecycle Management – Eliminate manual processes to ensure consistency and scalability.

3. Adopt Cloud-Native Solutions – Use platforms designed to handle modern workloads and machine identities.

4. Enforce Zero Trust – Continuously align permissions with actual needs to minimize risk.

Bradley emphasizes that these steps are sequential, visibility lays the groundwork for automation, monitoring, and governance at scale.

The Business Case for Unified Governance

A comprehensive identity governance strategy enables organizations to:

• Reduce breach risk by securing all identities.

• Improve operational efficiency via automation.

• Scale security without sacrificing agility.

Bottom Line

Identity governance is no longer optional, it’s a strategic imperative for cloud-era security. By embracing a unified, cloud-native approach, organizations can secure both human and machine access, reduce operational friction, and future-proof their IAM strategy.
