How Secure Is Your SharePoint Setup?
Misconfiguration and oversharing are common—and often invisible.
Understand the key SharePoint security risks facing UK organisations.
Old Risks Don’t Disappear on Their Own
Legacy systems, forgotten accounts, and outdated configurations quietly increase exposure.
This article explains how a legacy debt audit helps UK organisations uncover and reduce hidden risk.

When organisations adopt a new Software‑as‑a‑Service (SaaS) platform, the experience is intentionally smooth. Onboarding is guided, integrations are encouraged, and early results arrive quickly.
The real test, however, does not come at the beginning of the relationship. It comes at the end.
For many mid‑sized organisations across London and the South East, the “front door” of SaaS adoption is open and welcoming, but the exit is far less accommodating. Data exports are partial, key records are stored in proprietary formats, and migration frequently depends on paid vendor assistance.
This is more than a technical inconvenience. It is a governance and resilience risk.
As organisations prepare for a future shaped by automation, AI‑assisted workflows, and tighter regulatory expectations, control over data has become a strategic asset. If your data cannot be moved cleanly, securely, and independently, then your organisation’s timelines, costs, and options are being set externally.
A backup exit strategy is how leadership maintains leverage.
Why UK Organisations Need a Clear SaaS Exit Strategy in 2026
By 2026, most UK organisations with 30–400 users are no longer operating within a single system. Business data is distributed across:
- Primary SaaS platforms
- Line‑of‑business applications
- Third‑party integrations
- Automation and workflow tooling
- AI‑enabled services and agents
This level of SaaS sprawl means that replacing a vendor is rarely a simple procurement decision. It is a data‑movement exercise. If data cannot be extracted in a usable form, organisations do not “switch tools”- they absorb the risk and stay put.
This risk is amplified by today’s security landscape.
The Verizon 2025 Data Breach Investigations Report (DBIR) highlights the continued dominance of credential‑based attacks and unauthorised data access across analysed incidents worldwide.
In the UK, the National Cyber Security Centre (NCSC) consistently reinforces that attackers target access pathways – not just vulnerabilities – because they provide the fastest route to high‑value data.
This matters because data exits and migrations rely on the same pathways attackers target:
- Privileged access
- API tokens and service accounts
- Bulk data movement
- Administrative sessions
When a migration is required urgently – due to commercial pressure, compliance issues, or security concerns – organisations without a tested exit strategy are forced into rushed decisions.
A backup exit strategy prevents “we must move” from becoming “we cannot move safely.”
The Financial Cost of the Proprietary Trap
Vendor lock‑in rarely shows up as a single line item. Instead, it increases operational cost quietly and persistently.
When data cannot move easily:
- Tool consolidation becomes expensive
- Contracts renew by inertia rather than value
- Over‑licensing persists longer than necessary
- Strategic change requires full transformation projects
For organisations in London and surrounding regions, where labour, consulting, and downtime costs are already high, this lack of flexibility becomes a significant financial issue.
The real cost is not the platform itself. It is the loss of choice.
A well‑designed backup exit strategy reverses this dynamic. It enables leadership teams to:
- Compare vendors realistically
- Plan migrations on business timelines
- Reduce overlapping tooling
- Align IT spend with organisational priorities
In practical terms, it turns dependency into optionality.
Securing the Move: Why Exits Are High Risk Moments
Data migrations are not inherently unsafe but they concentrate risk.
During an exit or migration, organisations typically experience:
- Elevated privileged access
- Multiple concurrent admin sessions
- High‑volume data movement
- Temporary security exceptions
This is precisely the scenario modern attackers look for.
Microsoft’s Digital Defense Report documents the rise of adversary‑in‑the‑middle attacks, where session tokens are intercepted and reused to bypass MFA protections
Cloudflare has also highlighted how MFA bypass techniques appear as part of broader attack chains rather than isolated events.
For UK organisations subject to GDPR, the Information Commissioner’s Office (ICO) is clear that accountability and data protection must apply to data handling during migrations as well as normal operations.
To secure a backup exit migration:
- Use phishing‑resistant authentication for administrative and migration accounts where available
- Reduce session lifetimes for privileged access during the migration period
- Perform migrations from managed, patched, monitored devices
- Actively monitor for abnormal access, data spikes, and token misuse
Ownership Is a Discipline, Not a Feature
The organisations best positioned for the next phase of digital change will not simply adopt new tools. They will remain resilient as tools evolve, pricing changes, and risk profiles shift.
That resilience comes from:
- Clear data ownership
- Documented exit paths
- Tested export processes
- Security‑led migration planning
In an environment shaped by SaaS sprawl and AI‑driven workflows, control over data movement is what enables confident decision‑making.
