TL;DR: VDI and DaaS differ most in who controls infrastructure, how scaling happens, and where security responsibility sits, according to Island. For identity teams, the real issue is whether access governance, device trust, and compliance controls remain enforceable when desktop delivery moves into shared cloud operations.
NHIMG editorial — based on content published by Island: VDI vs. DaaS: What’s the difference?
By the numbers:
- 96% of organisations store secrets outside of secrets managers in vulnerable locations including code, config files, and CI/CD tools.
- Only 5.7% of organisations have full visibility into their service accounts.
- 71% of NHIs are not rotated within recommended time frames, increasing the risk of compromise over time.
Questions worth separating out
Q: How should security teams compare VDI and DaaS from an identity governance perspective?
A: Start by asking where authentication, session policy, privileged administration, and audit evidence are enforced.
Q: When does DaaS create more risk than VDI for IAM and PAM teams?
A: DaaS becomes riskier when the organisation cannot clearly enforce its own identity policy inside the hosted desktop, or when provider and customer responsibilities are poorly separated.
Q: What do teams get wrong about secure virtual desktop deployments?
A: They often focus on infrastructure strength and overlook identity boundaries.
Practitioner guidance
- Define the control boundary before selecting a desktop model Map which controls remain with the organisation and which move to the provider, then require explicit ownership for identity, endpoint posture, logging, patching, and incident response across the desktop stack.
- Review privileged access around desktop administration Treat desktop platform administrators as high-risk privileged users and place their access behind PAM, session recording, and approval workflows rather than relying on standing admin rights.
- Validate conditional access at the desktop entry point Require authentication, device trust, and session policy checks before users enter the desktop environment, especially for contractors, remote staff, and BYOD use cases.

Control placement matters more than desktop branding. VDI and DaaS are often debated as infrastructure alternatives, but the security question is where authority sits for identity, session control, and administrative privilege. If the organisation cannot clearly separate platform control from user access control, it will overestimate what the desktop model itself can secure. Practitioners should treat desktop delivery as an identity governance problem with infrastructure consequences, not the other way around.
A question worth separating out:
Q: Who is accountable when a virtual desktop platform fails an audit or security review?
A: Accountability depends on the model. In VDI, the organisation owns most of the control stack, so internal IT and security teams carry the burden. In DaaS, accountability is shared, but the organisation still owns user identity, access policy, and how sensitive work is authorised inside the desktop session.
