vCISO leadership, framework compliance and executive reporting — with one difference: your maturity is measured against how you’re actually attacked, not a self-assessment checklist.
Cybersecurity governance is how leadership directs and oversees the management of cyber risk — connecting security strategy to business priorities, regulatory duties like LGPD, and frameworks such as ISO 27001 and NIST CSF. Done well, it gives the board a clear, defensible answer to one question: how much cyber risk are we carrying, and is it under control? Mercurius delivers governance that’s grounded in evidence from real offensive testing — so the maturity you report is the maturity you actually have.
From executive leadership to the slide your board actually reads — each capability stands alone or works as a single, mapped program.
Senior security leadership on a fractional, interim or project basis — owning strategy, the security roadmap and the conversation with your board and auditors.
Risk assessments that rank threats by real business impact and exploitability — so investment goes where it reduces the most risk, not where the checklist points.
Implementation and readiness across the frameworks your customers and regulators demand — mapped so a single set of controls satisfies several obligations at once.
Executive reporting that turns control data into a story leadership can act on: posture, maturity trend, top risks and the decisions you need from them.
Most organizations need more than one. We map controls across them so you build once and report many.
| Framework | What it's for | Best when | Certifiable |
|---|---|---|---|
| ISO 27001 | Information security management system (ISMS) | You need an internationally recognized certificate | Yes |
| NIST CSF 2.0 | Risk-based security framework with a Govern function | You want a flexible maturity model, not a pass/fail | No (framework) |
| SOC 2 | Trust controls reported by an auditor | US customers ask for it in procurement | Attestation |
| PCI DSS | Cardholder data protection | You store, process or transmit card data | Yes |
| LGPD | Brazil's data protection law | You handle personal data of people in Brazil | Legal obligation |
NIST CSF 2.0 added the “Govern” function in 2024, putting board-level oversight at the center of the model.
Posture and maturity assessment, validated with offensive testing — we measure where you really stand, not where the questionnaire says.
A risk register ranked by business impact and exploitability, with a roadmap that puts budget where it reduces the most risk.
We lead implementation across frameworks and controls, interfacing with auditors, regulators and insurers on your behalf.
A recurring board cadence: maturity trend, top risks and the decisions leadership needs to make — in the language they speak.
It’s the structures, policies and accountability that let leadership direct and oversee how cyber risk is managed — connecting security strategy to business priorities, regulations like LGPD, and frameworks like ISO 27001 and NIST CSF. The goal is a defensible, board-level view of risk posture and maturity.
A vCISO (virtual Chief Information Security Officer) is an experienced security executive who leads your security program on a fractional or interim basis. You get CISO-level strategy, board reporting and program ownership without the cost and hiring lead time of a full-time executive.
ISO 27001, NIST CSF 2.0, SOC 2, PCI DSS and Brazil’s LGPD, plus readiness for cyber insurance and supply-chain security questionnaires. We map controls across them so one program satisfies multiple obligations.
We’re offensive-led. Maturity scores and recommendations are validated against how you’re actually attacked — through penetration testing, attack surface mapping and threat intelligence — rather than a self-assessment questionnaire. Decisions are grounded in real exploitability evidence.
Typically within days of scoping. The first phase is a posture and maturity assessment, followed by a prioritized roadmap and a recurring executive reporting cadence. Engagements are fractional, interim or project-based.
Yes. We operate across Brazil, Chile and the United States and deliver governance engagements and board reporting in Portuguese, Spanish and English.
