Security & Trust
Learn how S2E protects your account, processes your data, and safeguards taxpayer information in the RELIEF module.
Accounts are protected with secure sign-in and email verification. Access to RELIEF is limited to users with an active subscription.
Uploaded Excel files, transaction rows, validation results, and generated DAT files are processed in your browser and are not stored on S2E service storage. Account, subscription, payment verification, usage log, and company profile data may be stored when needed to provide the service.
S2E aligns its security roadmap with the NIST Cybersecurity Framework and ISO/IEC 27001 principles. This is a design commitment, not a certification claim.
How we protect your use of S2E
- Only signed-in users with active access can use the RELIEF workspace.
- Uploaded Excel files, transaction rows, validation results, and generated DAT files are processed locally in your browser without storing taxpayer transaction data on S2E service storage.
- Payment confirmation files are used only for subscription verification and support.
- Privacy, service terms, and data processing terms are presented before use.
- System activity may be logged to help investigate support issues and protect accounts.
Cybersecurity framework alignment
S2E uses the NIST Cybersecurity Framework and ISO/IEC 27001 principles as reference points for internal security reviews and its security roadmap, including access control, audit logging, data minimization, incident response, and continuous improvement. This is a framework-alignment statement and not a claim of ISO/IEC 27001 certification.
Customer responsibility
While S2E helps prepare and validate RELIEF files, customers remain responsible for reviewing taxpayer information, filing periods, and final BIR submissions.
