Case Studies
Security work that holds up under real-world pressure.
From central banks to global manufacturers, Intelleti has hardened the systems that institutions cannot afford to lose. These are ten of those engagements — the threats, the work, and the numbers that followed.
Case 01 / Banking
reduction in authentication-related security incidents
When the nation's central bank is the target, identity becomes the perimeter.
Intelleti partnered with the Central Bank of Oman to modernise identity and access controls across critical banking systems — replacing legacy authentication with a Zero-Trust model built to withstand credential-based attack and aligned to national cybersecurity directives.
The Challenge
- Legacy authentication mechanism exposing critical systems
- rising credential-phishing attempts
- regulatory pressure to strenthen identity governance
- secure access needed across distributed teams
our solution
- Designed a Zero-Trust IAM blueprint
- Deployed MFA with conditional access
- Introduced privileged-access governance
- Ran security awareness & adoption workshops
the impact
- 80% fewer authentication-related incidents
- Stronger compliance with national frameworks
- Hardened resilience of critical banking operations
Case 02 / FinTech
reduction in spoofed-domain attacks targeting the brand
Stopping fraudsters from wearing Revolut's name.
Intelleti helped Revolut shut down impersonation and payment-fraud attempts across its global operation by enforcing modern email authentication and giving security teams real visibility into who was sending mail in Revolut’s name.
The Challenge
- High volume of spoofed-domain attacks
- Limited visibility into authentication failures
- Payment-fraud attempts aimed at finance teams
our solution
- Implemented DMARC enforcement
- Hardened the secure email gateway
- Introduced impersonation-detection rules
- Delivered targeted awareness training
the impact
- 99% reduction in spoofed-domain attacks
- Sharp drop in payment-fraud attempts
- Greater staff confidence identifying threats
Case 03 / Retail
improvement in mean time to respond (MTTR)
Turning alert fatigue into decisive response.
Intelleti modernised Tesco’s Security Operations Centre — re-engineering detection, automating triage and equipping analysts to hunt threats rather than drown in noise, with the whole operation realigned to ISO 27001.
The Challenge
- High false-positive alert volume
- Slow response to critical threats
- Limited threat-hunting capability
our solution
- Built new SIEM detection rules
- Introduced automated triage workflows
- Delivered threat-hunting playbooks
- Trained SOC analysts
the impact
- 55% reduction in false positives
- MTTR improved by 40%
- SOC aligned with ISO 27001
Case 04 / Healthcare
reduction in phishing susceptibility across staff
The strongest firewall is a workforce that knows what to look for.
Intelleti delivered a year-long behavioural change programme for NHS Scotland, reducing human-factor incidents across clinical and non-clinical teams through role-based training, live phishing simulations and measurable human-risk KPIs.
The Challenge
- High staff turnover
- Frequent phishing incidents
- Limited awareness of data-handling risks
our solution
- Designed role-based training
- Delivered phishing simulations
- Introduced human-risk KPIs
- Updated policies and procedures
the impact
- 70% reduction in phishing susceptibility
- Improved incident reporting
- Stronger compliance with NHS standards
Case 05 / Banking
reduction in cloud misconfigurations
Governing the cloud at the speed of adoption.
As a major UAE bank scaled rapidly into the cloud, Intelleti built the governance framework to keep pace — establishing risk-based controls aligned to NIST and regional regulation, and turning ad-hoc cloud usage into an audit-ready operation.
The Challenge
- Rapid, unstandardised cloud adoption
- Mounting regulatory pressure
- No consistent cloud processe
our solution
- Built a cloud governance framework
- Introduced risk-based controls
- Delivered cloud-security training
- Conducted architecture reviews
the impact
- Achieved regulatory compliance
- 35% fewer misconfigurations
- Markedly improved audit readiness
Case 06 / Legal
Tabletop-Tested
incident response, built around legal confidentiality
Privileged client data demands more than a plan on paper.
Intelleti gave Clifford Chance a tested incident-response capability — moving the firm from no formal plan to rehearsed playbooks, sharper monitoring and teams that know exactly what to do when sensitive client data is at risk.
The Challenge
- No formal IR plan
- High ransomware risk
- Limited monitoring capability
our solution
- Built IR playbooks
- Conducted tabletop exercises
- Improved SIEM visibility
- Trained legal and IT teams
the impact
- Faster response to incidents
- Improved ransomware preparedness
- Strengthened client trust
Case 07 / Telecom
reduction in manual alert triage
Automating defence across one of Africa's largest networks.
As Intelleti modernised threat detection for MTN Group, one of Africa’s largest telecom providers — building automated response workflows and sharper detection across a vast attack surface, while integrating cleanly with legacy infrastructure.
The Challenge
- Large attack surface
- High alert volume
- Limited automation
our solution
- Built automated response workflows
- Enhanced detection rules
- Delivered SOC training
the impact
- 50% reduction in manual triage
- Improved detection accuracy
- Strengthened telecom resilience
Case 08 / Insurance
reduction in account-compromise attempts
MFA only works when people actually use it.
Intelleti rolled out multi-factor authentication across Aviva in three months — not just deploying the technology, but winning adoption across non-technical teams so that credential-stuffing and password reuse stopped translating into compromise.
The Challenge
- Widespread password reuse
- Credential-stuffing attempts
- Staff resistance to MFA
our solution
- Rolled out MFA organisation-wide
- Delivered adoption workshops
- Updated access policies
the impact
- 90% reduction in account-compromise attempts
- Improved user confidence
- Strengthened compliance posture
Case 09 / Manufacturing
Segmented
OT environment with a reduced attack surface
Privileged client data demands more than a plan on paper.
Intelleti assessed and hardened operational technology across Airbus manufacturing — confronting outdated OT systems and flat, unsegmented networks to cut operational risk and build a response plan for the environments where downtime is not an option.
The Challenge
- Outdated OT systems
- No network segmentation
- High operational risk
our solution
- Conducted an OT risk assessment
- Introduced a segmentation strategy
- Delivered an OT incident response plan
the impact
- Reduced OT attack surface
- Improved operational resilience
- Strengthened compliance with EU regulations
Case 10 / Banking
reduction in security incidents
Building security in — before scale makes it impossible.
As Monzo scaled fast, Intelleti embedded security-by-design into how the bank builds and operates — a secure SDLC, risk-based controls, developer training and modern identity that let the team ship quickly without trading away governance.
The Challenge
- Rapid scaling
- Limited internal security processes
- Investor pressure to show maturity
our solution
- Built a secure SDLC framework
- Introduced risk-based controls
- Delivered developer training
- Implemented IAM and MFA
the impact
- Faster, more secure product releases
- Improved investor confidence
- 60% reduction in security incidents
