Specialist consulting in authorization design, role redesign, SOD remediation, and GRC access control — delivered globally.
Open the live platform ↗How SAP security and audit work changes with Rinexis. Before Rinexis: the work is scattered across disconnected tools — an Outlook inbox of access requests, an Excel access-review spreadsheet, the SAP Logon GUI, a SOD-matrix PDF, a Microsoft Teams approvals channel, and a folder of audit evidence — with no single interface tying them together. After Rinexis: those tools converge into one connected console — access reviews become a live Sodly conflict with execution evidence and a one-click Send to Roleforge, the fix is proven against the live SOD engine (2 resolved, 0 introduced, coverage 100 percent) and exported as AGR_1251, Tcodex surfaces the hidden ZME23-to-ME23N wrapper, and email, spreadsheets and SAP exports are connected as integrations with evidence filed straight to the workpaper.
From S/4HANA migrations to global role redesign programs, Rinexis helps enterprises reduce risk, simplify authorization models, and stay audit-ready.
See it live on getrinexis.com ↗Every role, assignment, and segregation-of-duties conflict — inventoried and ranked by what actually puts you at risk.
Roles rebuilt around how you actually work — then proven conflict-free against a live SOD engine before they ever ship.
Access matrices, SOD resolution, and control evidence — packaged to withstand SOX, GDPR, and internal scrutiny.
Humans, copilots, agents, and integrations — every identity routed through approved, monitored access gates.
Excessive access and segregation-of-duties conflicts sit quietly inside your system until an audit exposes them. We inventory every role, assignment, and conflict — then rank it by what actually matters — so your exposure is visible before it becomes a finding.
Your old roles can't make the trip. We rebuild your authorization model for the new architecture — Fiori, BTP, and all — so security isn't the thing that delays go-live.
Access and SOD findings are the most common way SAP audits fail. We get your roles, matrices, and evidence audit-ready before the auditor arrives — not during.
Years of quick fixes leave thousands of overlapping roles and hidden conflicts. We collapse the sprawl into a clean, least-privilege model your team can actually maintain.
Manigandan founded Rinexis to do one thing without compromise: SAP security, led by someone who has actually done the work. Across 13+ years he has built authorization models from the ground up, untangled segregation-of-duties conflicts at scale, and carried enterprises through SOX, GDPR, and internal audit. He leads every engagement personally — clients get the practitioner, not a junior trading on his name.
Shyam works on the build side of the practice — authorization design, role build and testing, and S/4HANA security migrations. He's the one making sure a model that looks right on paper actually holds up in production, and that go-lives aren't held up by security.
Vignesh works across the core of SAP access control — SOD validation, role redesign, and GRC Access Control configuration. He focuses on turning sprawling, accidental role catalogues into clean least-privilege models, and on producing the access evidence that holds up when audit comes knocking.
From a rapid diagnostic to continuous governance — each engagement is scoped to deliver clear, documented outcomes from day one.

For you if you're migrating, prepping for audit, or your roles have stopped making sense.
