Validate whether an attacker can reach customer data, move between tenants, or change a business outcome. Eresus Security scopes the work in writing, tests approved paths, and returns evidence your engineers can reproduce.
Southeast Asia's financial and tech center. MAS Technology Risk Management Guidelines and Personal Data Protection Act drive cybersecurity investments.
A penetration test starts with ownership, not tooling. We confirm which hosts, applications, identities, and environments are in scope, who can authorize state-changing actions, and how production impact is contained. Testing outside those boundaries is not part of the engagement.
Written authorization, test windows, contacts, and escalation rules
Dedicated test accounts and synthetic records where possible
Production safeguards and explicit exclusions for destructive actions
Technical observations that can support internal MAS TRM, PDPA, or PCI DSS work without claiming certification
Test attack paths, not scanner categories
Coverage follows how the application authenticates users, separates tenants, and moves money or data. We chain weak authorization, session behavior, business logic, and integration trust where a single finding would understate the risk.
Authentication, session, MFA, and account-recovery behavior
Object- and function-level authorization across roles and tenants
Business logic, replay, rate limits, and state transitions
Web, API, and internal service boundaries within the agreed scope
Deliver evidence engineering can close
Each confirmed issue is tied to the request sequence, tested identity, affected resource, business impact, and the smallest safe reproduction. Scanner observations are separated from validated claims, and agreed fixes are retested against the original path.
Prioritized findings with an accountable remediation owner
Reproduction steps that avoid exposing real customer data
Clear distinction between confirmed access and theoretical risk
Retest notes that show whether the attack path is actually closed
