CyberOne Assure365 Identity as a Service:
Pros & Cons
Pros:
- Access to NCSC-assured, Microsoft-certified Identity & Access Management Advanced specialisation without recruitment challenges.
- SLA-backed response times and guaranteed security outcomes from CyberOne's accredited team.
- Ongoing policy optimisation and alignment with compliance are included in the service.
Cons:
- While initial onboarding and knowledge transfer are required, CyberOne's structured process is designed to minimise disruption during this phase (advantage: reduced disruption; disadvantage: initial transition required).
- Some organisations may prefer to retain all identity management in-house for cultural reasons. The service can offer co-management options to maintain desired internal control (advantage: flexibility; disadvantage: possible preference for full control).
- The service focuses on Microsoft Entra ID. Organisations with non-Microsoft platforms may need separate solutions (advantage: specialised Microsoft expertise; disadvantage: may not cover other platforms).
Now, let's examine what it means to manage Microsoft Entra ID entirely in-house.
In-house Entra ID management means your own IT team configures, monitors and maintains Microsoft Entra ID directly. You retain full control over every policy, conditional access rule and user lifecycle process. The trade-off is that your team needs the right skills, time and tooling to do it well.
In-House Entra ID Key Features
- Direct Administrative Control: Your team makes all configuration decisions and can respond to changes immediately without external coordination.
- Microsoft Licensing Flexibility: You can choose from Entra ID Free, P1 or P2 tiers based on your feature requirements and budget.
- Native Microsoft 365 Integration: Entra ID connects natively with your existing Microsoft 365 and Azure workloads.
- Self-Service Password Reset: Users can reset their own passwords, reducing helpdesk tickets if configured correctly.
- Conditional Access Policies: You can create custom rules based on user risk, device compliance and location if you have the expertise to configure them.
In-House Entra ID Pros & Cons
Pros:
- You gain full visibility and control over your identity environment without external dependencies (advantage: autonomy; disadvantage: greater internal responsibility).
- Integration with existing IT operations and change management processes is seamless, but relies on in-house capacity to maintain (advantage: seamless integration; disadvantage: internal effort required).
- You have direct access to Microsoft support and documentation for troubleshooting (advantage: immediate escalation; disadvantage: may require in-depth internal expertise).
Cons:
- Mid-sized organisations average a security score of 52 out of 100 in hybrid identity environments, according to Semperis.
- UK identity management skills gaps mean that recruiting and retaining Entra ID specialists can take months (disadvantage: slower recruitment; advantage: internal career growth opportunities).
- Configuration drift and policy inconsistencies can accumulate without dedicated governance resources (disadvantage: requires consistent oversight; advantage: total internal control if resources exist).
Assure365 Identity as a Service vs In-House Entra ID: In-depth Comparison
Skills & Resourcing
Finding and keeping identity specialists is one of the hardest challenges for UK mid-market organisations right now. CyberOne gives you access to a Microsoft Security Elite Partner with Microsoft Intelligent Security Association Membership and a Microsoft Managed XDR Verified Solution .
In-house teams often share identity responsibilities across multiple IT functions, creating gaps in identity management.If your team is already stretched, a managed approach frees up capacity for strategic projects. If you have dedicated identity staff with time to focus, in-house management can work, but the skills investment is ongoing.
Configuration & Governance
CyberOne applies a structured approach to conditional access, privileged identity management and access reviews. These configurations are tuned and monitored on an ongoing basis.
In-house, the same capabilities exist in Entra ID P2, but research consistently shows that many organisations don't fully configure them.The difference is whether the features you're paying for are actually protecting you. CyberOne's governance model ensures policies stay aligned with your risk profile and UK compliance requirements.
UK Compliance Alignment
Regulations like GDPR, FCA rules and NHS DSPT all have identity and access management implications. CyberOne's service is built around UK compliance requirements, with joiners, movers and leavers processes designed to support audit readiness. The NCSC's identity guidance recommends robust lifecycle management and strong privileged-user controls.
In-house teams can achieve the same outcomes, but they need to build compliance frameworks from scratch and maintain them. CyberOne handles this as part of the standard service delivery.
24×7x365 Monitoring & Response
Identity-based attacks don't follow office hours. CyberOne's CREST-accredited SOC monitors your Entra ID environment around the clock, detecting risky sign-ins, compromised credentials and suspicious behaviour. This aligns with Microsoft's finding that enabling multi-factor authentication can block over 99% of account compromise attacks.
Building 24×7 identity monitoring in-house demands major investment in people, processes and tooling. For most mid-market organisations, managed services provide clear value.
Total Cost of Ownership
The in-house cost isn't just the Entra ID licence. It includes recruitment, training, tooling and the opportunity cost of your team's time.
This creates a risk that has real financial consequences.CyberOne's managed service gives you predictable monthly costs and reduces the hidden expenses associated with identity mismanagement. For many organisations, the total cost of ownership is lower than a fully in-house approach once you factor in risk reduction.
If you're unsure about your current Entra ID setup, here are some assessment tips.
Most UK mid-market organisations assume their Microsoft Entra IDs are secure because they're running. In practice, assessments consistently reveal configuration gaps. Common issues include conditional access policies with too many exclusions, dormant accounts that were never deprovisioned and MFA not enforced for all user types.
A good starting point is to review your Microsoft Secure Score and compare it against industry benchmarks. You can also look at your access reviews and ask when they were last completed. If the answer is "never" or "we're not sure," that's a signal.CyberOne offers security assessments that benchmark your current Entra ID configuration against best practices and identify specific remediation steps.
It's also vital to recognise which identity risks matter most to UK mid-market organisations.
Identity has become the primary attack surface. Attackers target credentials because they're often the easiest path into your environment. Once inside, compromised identities can move laterally across your Microsoft 365 tenant, Azure resources and connected applications.For UK mid-market organisations, the risks that matter most include:
- Credential Theft & Phishing: Over 80% of breaches involve compromised identities or weak authentication controls, according to the Microsoft Digital Defence Report 2025.
- Dormant Accounts: Employees leave, but their access lingers. These accounts become entry points for attackers.
- Privilege Creep: Users accumulate permissions over time as they move between roles. Without regular access reviews, this creates unnecessary risk.
- Shadow IT: Users sign up for cloud services using corporate credentials, creating identity sprawl outside your governance perimeter.
CyberOne's Assure365 Identity as a Service addresses each of these risks through proactive monitoring, automated lifecycle management and ongoing governance.
