Breach and Attack Simulation
That Proves Your Controls
Work Every Day
Breach and attack simulation
Continuous, Safe Validation of Your Security Controls
Security controls drift as environments change. Breach and attack simulation (BAS) safely and repeatedly tests whether your email, web, endpoint and network defences still prevent and detect realistic threats. iSpyCyber designs, runs and interprets BAS programmes so your team gets clear, prioritised evidence of what works and what needs attention.
Why organisations choose iSpyCyber
Continuous assurance
Controls are validated on a regular schedule, not just once a year.
Safe by design
Simulations use benign, controlled payloads that never damage systems or data.
ATT&CK aligned
Scenarios map to MITRE ATT&CK, so results link directly to detection gaps.
Control efficacy scoring
See which controls prevent, detect or miss each simulated behaviour.
Expert interpretation
Our specialists explain results and recommend fixes, not just raw scores.
Fits your CTEM programme
Results feed continuous threat exposure management alongside iefyx.
Coverage
What We Validate
Simulations cover the control layers an attacker would need to get past, from initial access to data leaving your network.
Email security
Whether gateways and filters stop simulated malicious attachments and links.
Web security
Proxy, DNS and web filtering controls against simulated malicious destinations.
Endpoint protection
EDR and antivirus prevention and detection of simulated behaviours.
Network controls
Firewall and segmentation rules between critical zones.
Lateral movement detection
Visibility of simulated internal movement between systems.
Data loss prevention
Whether DLP and egress controls catch simulated data leaving your environment.
Cloud controls
Configuration and detection controls in your cloud tenancies.
SIEM and SOC alerting
Whether simulated activity produces the right alerts for your analysts.
Control drift
Changes in control effectiveness over time as your environment evolves.

Effort distribution
Where the programme time goes
After a short set-up, most effort goes into running simulations and turning results into prioritised improvements. Percentages are indicative.
Quality built into every phase
Authorised and scoped
Written authorisation and rules of engagement before any activity.
Safety first
Agreed stop conditions protect people, systems and data.
Evidence-based
Every conclusion is backed by timestamped evidence.
Improvement confirmed
Follow-up validation proves defences got better.
