Financial Services Managed Cloud Security

Fast-Growing Fintech Secures Microsoft 365

45 employees

The Challenge

A rapidly scaling fintech startup had a misconfigured Microsoft 365 environment that posed serious security risks. No multi-factor authentication was enforced, admin accounts had excessive privileges, and there was no email security filtering in place—leaving the organisation wide open to phishing and account compromise.

Our Solution

Prism conducted a full M365 security assessment and implemented conditional access policies, enforced MFA across all accounts, restructured admin roles using least-privilege principles, and deployed advanced email filtering to block phishing and malware before it reached inboxes.

The Results

  • Zero successful phishing incidents in 6 months
  • Cyber Essentials certification achieved
  • 100% MFA adoption across all user accounts
  • Admin accounts reduced from 12 to 3 with scoped permissions
Technology / SaaS Security Monitoring

SaaS Startup Gets 24/7 Visibility

30 employees

The Challenge

A 30-person SaaS company had no security monitoring in place whatsoever. The team was operating completely blind to threats—with no visibility into endpoint activity, cloud logs, or suspicious behaviour across their infrastructure.

Our Solution

Prism deployed Wazuh SIEM across all endpoints and cloud services, providing centralised log collection and real-time threat detection. Automated alert triage was built using n8n workflows, ensuring that genuine threats were escalated immediately while reducing noise from false positives.

The Results

  • 3 real threats detected and contained in the first quarter
  • Mean detection time under 15 minutes
  • 85% reduction in alert noise through automated triage
  • Full visibility across endpoints and cloud infrastructure
E-commerce / Retail Consulting

E-commerce Company Achieves SOC 2 Readiness

60 employees

The Challenge

A growing e-commerce business needed SOC 2 Type II certification to unlock enterprise customer contracts. Without dedicated security leadership, the team had no clear path to compliance—lacking formal policies, evidence-gathering processes, and a structured security programme.

Our Solution

Prism provided vCISO services to lead the compliance initiative end-to-end. This included a comprehensive gap analysis, development of security policies and procedures, implementation of required controls, and systematic evidence gathering to satisfy audit requirements.

The Results

  • SOC 2 Type II audit passed on first attempt
  • Unlocked £2M enterprise sales pipeline
  • 23 security policies developed and implemented
  • Ongoing compliance programme established for annual renewal
