Cybersecurity

Every modernization initiative expands the attack surface. Cloud migrations introduce new access points. AI deployments create new data flows. Systems replacements expose vulnerabilities that legacy integrations have kept hidden. Organizations that modernize without security involvement in the architecture process tend to find the gaps later, when they are more expensive to close. TSG's security work is structured to run alongside program delivery so posture and progress move together.

Build a resilient enterprise

Close critical vulnerabilities at every phase of modernization 

Modernization creates new opportunities, but it can also introduce new risks. TSG combines cyber expertise, proven frameworks, and hands-on delivery to address critical vulnerabilities, strengthen resilience, and keep security aligned as your technology environment evolves.  

 

Visibility that keeps up with a changing environment 

As cloud workloads are added, AI tools are integrated, and vendor connections expand, the environment changes faster than static detection approaches can keep up with. We design detection aligned to where the environment is going, not just where it is today.
 
Core capabilities:
  • Security architecture designed alongside infrastructure decisions  
  • Threat visibility updated as new workloads and integrations come online  
  • Response readiness confirmed at program milestones before go-live  
  • Detection built for the target environment, calibrated as the environment evolves   
  • Security operations support scoped to program phase and internal team capability

Governance, risk, and compliance

Design and operationalize security governance that aligns risk, compliance, and business priorities while enabling proactive oversight and regulatory confidence without slowing delivery. 
 
Core capabilities:
  • Risk posture assessed against the future state environment, not just the current one  
  • Regulatory requirements mapped into program scope before delivery begins 
  • Control frameworks designed to cover the environment through and after transition  
  • Risk tracking maintained across program phases 
  • Governance structured to inform delivery decisions without creating bottlenecks 
 

System hardening and secure configuration

Assess and secure hardware, firmware, embedded systems, and connected devices across IT and operational environments to establish resilient, adaptive protection without disrupting operations. 
 
Core capabilities:
  • Configuration baselines established before workloads migrate into new environments IT and OT security aligned during infrastructure transitions 
  • Legacy and embedded systems assessed and hardened as part of migration scope 
  • Configuration integrity maintained as environments change to prevent drift from creating exposure

Governance and control at every step of modernization

Across assessment, design, migration, and steady state, we establish the controls and governance your teams need to modernize confidently while keeping critical services resilient and secure.

CASE STUDY

 

End-to-end compliance and security in under 30 days

When a financial services leader faced a large merger, TSG mobilized in less than 30 days to deliver end-to-end GRC testing, SOX compliance, and secure application validation under tight deadlines.
