What is Okta and Why Does Your Business Need It?

Onboarding new staff manually is one of the most time-consuming and error-prone processes in a growing business. Before a new employee can do any work, someone has to create their email account, add them to Slack, grant them access to your project management tool, invite them to your HR platform, set up their GitHub account and configure their single sign-on. Every step is manual, has to be done by a human and depends on someone else doing something on time.

Now think about what happens when that same employee leaves. Every account they ever had needs to be revoked. Every application they ever accessed needs to be closed off. In most businesses, some of those accounts are still active weeks or months after the person left. A few will never be closed at all.

This is the identity problem. Automated onboarding through a platform like Okta removes the manual steps entirely and replaces them with a policy-driven system that works consistently regardless of how many people join, leave or change roles. And it is one of the most common and most costly operational and security failures in modern businesses.

Okta exists to solve it.

What is Okta?

Okta is an identity platform, sometimes referred to as identity as a service. It is the central layer that connects your people to every application, system and resource they need to do their job, ensuring that the right people have the right access at the right time, automatically.

Okta enables single sign-on, multi-factor authentication, lifecycle management and API access management, helping organisations control who has access to applications, resources and data.

In practical terms, Okta sits between your employees and every application your business uses. When someone joins, Okta provisions their access automatically as part of a complete user lifecycle management workflow. Departures trigger automatic revocation. Role changes update permissions instantly. At every login, Okta verifies the user’s identity and enforces your security policies before granting access.

It sounds simple. The impact on how a business operates and how securely it runs is anything but.

The problem Okta solves

Most businesses manage identity badly. Not because they are careless, but because identity management was never designed to scale with the way modern businesses operate.

Ten years ago, a business might use five or six applications. Today the average business uses dozens. Each application has its own login, its own password, its own access control. The employee onboarding process for a new hire means someone manually adding them to each one. When they leave, someone manually removes them from each one.

The failure rate on both processes is high. New hires wait days for access to tools they need from day one. Remote employee onboarding is even harder, a new starter based outside the UK, working from Porto or Berlin, has no way to chase IT in person when their access has not been set up. Former employees retain access to systems they should no longer be able to reach. IT teams spend hours each week on manual provisioning tasks that add no strategic value.

Instead of managing users and permissions in multiple tools, Okta provides a single source of truth for identity, reducing administrative overhead and errors. Features like SSO, MFA and adaptive policies reduce the risk of compromised credentials while still keeping access convenient for users.

The security implications are equally serious. Every orphaned account from a departed employee is a live credential that could be used to access your systems. Applications without MFA enforced are potential entry points. Any manually managed access list will eventually be wrong.

Okta removes the manual process entirely and replaces it with an automated, policy-driven system that works consistently regardless of how many people join, leave or change roles.

How Okta works in practice

Single sign-on

Single sign-on means your employees log in once and get access to everything they are authorised to use. One set of credentials. One login prompt. Every application, from Google Workspace to Slack to Salesforce to GitHub, accessible from a single Okta dashboard without separate passwords.

Employees benefit from less friction and no password fatigue. IT teams get one place to manage access rather than dozens of separate admin consoles. For security teams, every login goes through Okta’s authentication layer where policies are enforced consistently.

Multi-factor authentication

Okta’s MFA enforces additional verification at sign-in, requiring employees to confirm their identity through a second factor such as an authenticator app, a push notification or a hardware key.

Multi-factor authentication is no longer optional for UK businesses. Cyber Essentials v3.3, the updated framework that came into force in April 2026, makes MFA on all cloud services an automatic failure point at certification. Every account without MFA enforced is a gap in your compliance posture.

Okta enforces MFA centrally across every connected application. Rather than enabling MFA separately in each app, you configure the policy once in Okta and it applies everywhere. When a new employee is provisioned as part of the onboarding process, MFA is enforced from their very first login without any additional IT steps.

Automated user provisioning and deprovisioning

This is where Okta delivers its most significant operational impact and where automated employee onboarding becomes a reality rather than an aspiration.

When a new hire is added to your HR system, Okta receives the signal and automatically provisions their access across every application as part of a complete user lifecycle management workflow. Google Workspace account created. Slack access granted. GitHub organisation membership added. Project management tool access configured. All of it happens automatically, before the employee starts, without a single IT ticket being raised.

For remote employees joining from outside the UK, whether in Porto, Berlin or anywhere else, remote employee onboarding through Okta works identically. Access is provisioned before they start, regardless of where they are based. The new hire opens their laptop on day one and everything is ready. There is no waiting, no chasing IT and no days lost to manual setup.

When that employee leaves, the reverse happens. One action in your HR system triggers Okta to revoke access everywhere simultaneously. There are no manual steps, no orphaned accounts and no ex-employees logging into your systems because someone forgot to remove them.

For businesses that have read our guide to the perfect employee onboarding process, this is the engine that makes zero-friction onboarding possible. The automation does not happen by magic. It happens because Okta is configured correctly, integrated with your HR system and mapped to the right application access for each role.

Role-based access control

Okta manages access through groups and roles. A developer gets access to GitHub, your cloud infrastructure and your monitoring tools. A finance employee gets access to your accounting platform, your expense tool and your reporting dashboards. A new starter in operations gets their specific set.

When someone changes role, their group membership changes and their access updates automatically. They gain what they need and lose what they no longer should have. No manual review. No access creep where employees accumulate permissions they should have lost when they moved teams.

Automated user provisioning and deprovisioning, role-based access controls and detailed audit trails help organisations address compliance requirements and reduce security risks associated with manual access management.

Integrations

Okta offers more than 8,200 pre-built integrations covering the applications and services most businesses rely on. Google Workspace, Microsoft 365, Slack, Salesforce, GitHub, Jira, Zoom, HubSpot, Xero, if your business uses it, Okta almost certainly has a pre-built integration that handles provisioning, SSO and deprovisioning automatically.

For less common applications, Okta’s API and SCIM support allows custom integrations to be built. The breadth of the integration catalogue is one of the primary reasons businesses choose Okta over building identity management in-house or relying on a patchwork of individual application settings.

Why businesses choose Okta over alternatives

The identity management market has several options. Microsoft Entra ID is the natural choice for businesses built entirely around the Microsoft ecosystem. Google Workspace has built-in identity management for Google-first businesses. JumpCloud and other platforms offer similar capabilities at different price points.

Okta’s primary differentiator is that it is platform-neutral. It works equally well across Mac and Windows, across Google Workspace and Microsoft 365, across any combination of cloud applications regardless of vendor. For businesses running a mixed environment – which describes most UK businesses at the 20 to 200 employee scale, Okta provides a single identity layer that works across everything rather than being tied to one vendor’s ecosystem.

For businesses running Apple devices specifically, Okta integrates directly with Apple Business Manager and MDM platforms like Jamf Pro and Iru. When a Mac is enrolled in MDM and the user logs in with their Okta credentials, the device and the identity are linked. Conditional access policies can enforce that only enrolled, compliant devices can access specific applications. A personal laptop cannot reach your corporate tools even with valid credentials.

Okta and Cyber Essentials compliance

For UK businesses pursuing or maintaining Cyber Essentials certification, Okta directly addresses several of the five technical controls.

Access control is one of the five controls. Cyber Essentials requires that users only have access to what they need for their role. Okta’s role-based access control and automated provisioning make this demonstrably true at assessment time. Rather than manually reviewing who has access to what, you can pull an Okta report showing exactly who has access to each application and why.

Cyber Essentials MFA requirements are now mandatory under v3.3 for all cloud services. Okta enforces MFA centrally across every connected application, making compliance a configuration rather than an ongoing manual effort.

Secure configuration is also addressed. Okta’s conditional access policies can enforce that only devices meeting your security requirements, enrolled in MDM, encrypted and up to date, can access corporate applications. This strengthens your device security posture in a way that is auditable and consistent.

For businesses that need to demonstrate compliance not just at certification time but continuously, Okta’s audit logs provide a complete record of every authentication event, every access grant, every policy change. If a question arises about who accessed what and when, the answer is in Okta.

Okta and the full employee lifecycle

The clearest way to understand Okta’s value is to map it against the full employee lifecycle. This is where identity as a service moves from a technical concept to a measurable business outcome.

Joining – automated onboarding from day one

New hire added to HR system. Okta provisions Google Workspace account, assigns group memberships based on role, pushes app access to their Okta dashboard and enforces MFA on first login. The induction schedule for new employees can focus entirely on culture, role and relationships rather than IT setup. Not a single ticket raised, no manual steps taken and no days lost waiting for access.

For remote employee onboarding specifically, this is transformative. The new hire in Porto logs on, their Okta dashboard shows every application they need, Google Workspace is fully configured and Slack is ready. The onboarding new staff experience is identical whether someone starts in the London office or joins remotely from anywhere in the world.

Role change – access that follows the person

Employee moves from engineering to product. HR system updated. Okta adjusts group memberships automatically. GitHub organisation access changes. Infrastructure tools removed. Product management tools added. Access reflects the new role within minutes of the HR update.

Leaving – complete and immediate deprovisioning

Employee gives notice. HR system updated with departure date. Okta deprovisions access across every connected application on that date. Google Workspace suspended. Slack access revoked. GitHub removed. Every application closed simultaneously. No orphaned accounts.

Security incident – instant response

A device is reported lost or stolen. IT suspends the user’s Okta session. All active sessions across every application are terminated immediately. The device can no longer be used to access corporate systems regardless of what credentials are stored on it.

Once Okta is set up it runs smoothly without day-to-day intervention, making things easier for admins who benefit from better organisation of access and authentication, and for users who benefit from simpler logins through SSO

Building an onboarding checklist around Okta

A well-structured staff onboarding checklist built around Okta looks different from a manual process. Rather than a list of IT tasks to complete, it becomes a list of configurations to verify.

Before the employee starts: confirm Okta account provisioned, group memberships assigned, Google Workspace accessible, MFA policy active, app assignments correct for role.

Day one: confirm single sign-on working on first login, all applications accessible from Okta dashboard, MFA enrolled in first session, device enrolled in MDM and linked to Okta identity.

First week: confirm access correct across all tools, no missing application assignments, device compliance confirmed in MDM.

When this checklist is consistently green, the new employee onboarding process works every time. Not most of the time. Every time.

Is Okta right for your business?

Okta is not the right fit for every business at every stage. Here is an honest picture of where it makes most sense.

Okta makes sense when your business uses more than ten cloud applications and managing access across them manually is becoming a source of IT overhead and security risk.

Growing businesses find it valuable when the cost of manually onboarding new staff is measurable in hours per week. For businesses pursuing Cyber Essentials certification, Okta provides the consistent access control and MFA enforcement the assessment requires. Mixed Mac and Windows environments benefit from a single identity layer that works across both platforms. And if a former employee still has access to systems they should not, that is perhaps the clearest signal that a structured identity platform is overdue.

If several of those describe your business, Okta is worth serious consideration. The configuration and integration work to implement it correctly requires expertise. Mapping roles to application access, integrating with your HR system, connecting your Apple MDM environment and building the provisioning workflows is a project, not a plug-in. But once it is in place, the operational and security return is substantial.
