Validate the API paths behind payments, customer accounts, and partner integrations. Eresus Security tests what an attacker can actually access and change, then gives your engineers evidence they can reproduce.
Southeast Asia's financial and tech center. MAS Technology Risk Management Guidelines and Personal Data Protection Act drive cybersecurity investments.
We agree the authorized hosts, environments, accounts, and transaction boundaries before testing. Coverage follows real application workflows instead of treating an API inventory as the whole attack surface.
Object- and function-level authorization, including cross-tenant access
Authentication, token scope, session handling, and recovery flows
Business logic, rate limits, replay, and state-transition abuse
GraphQL, REST, and service-to-service integrations in the agreed scope
Evidence your team can act on
Each confirmed issue is tied to a request sequence, affected identity and resource, business impact, and a safe reproduction. We separate exploitable paths from scanner observations and retest agreed fixes.
Prioritized findings with the affected endpoint and authorization boundary
Reproduction steps using approved test accounts and non-production data where possible
Remediation guidance mapped to the responsible application or platform team
Retest notes that show whether the original attack path is closed
Singapore scope and delivery
For Singapore-based teams, scoping can include payment and fintech workflows, SaaS tenant boundaries, and regional partner APIs. We can map technical observations to your internal MAS TRM, PDPA, or PCI DSS control work; this is a technical security assessment, not a compliance certification or legal opinion.
Agree data handling, test windows, contacts, and escalation rules up front
Keep production-impacting actions out of scope unless explicitly authorized
Deliver findings to engineering and security owners in a remediation-ready format
