CISO & GOVERNANCE
When your company needs a CISO
The CISO is the executive responsible for information security. Not every company needs one full time, but almost all of them need someone playing that role. Here are the signs, the options and how to get started.
IN 30 SECONDS
- A CISO turns security into business risk management, reporting to the board.
- Customer requirements, the LGPD, growth and incidents are the most common triggers.
- Piling the role onto the IT team usually leads to conflicts and a lack of time.
- CISO as a Service delivers the leadership without the cost of a full-time executive.
What a CISO does
The CISO (Chief Information Security Officer) is accountable for the information security strategy. They are not the person who installs the antivirus: they decide which risks are acceptable, where to invest, which policies apply across the company and how the organization reacts to an incident. Their job is to translate security into business language for the board.
- Strategy
A security plan aligned with the company’s goals and risk appetite. - Governance
Policies, standards, roles and indicators, based on frameworks such as NIST CSF and ISO 27001. - Risk
A map of business risks, with owners and treatment plans. - Response
Preparing for incidents and taking the lead when they happen.
Signs that your company needs a CISO
- Customers have started asking
Security questionnaires, contract clauses and audits from larger customers have become part of the sales process. - The LGPD is on the agenda
There is a large volume of personal data and nobody is truly accountable for protecting it or for handling incidents. - The company has grown
More people, systems, cloud services and vendors. What used to be simple now has many doors. - There has already been an incident
A data leak, scam or attack showed a lack of preparation and of someone in charge. - The board asks and nobody can answer
“Are we protected?” has no objective answer backed by numbers.
The three options, side by side
| IT takes on the role | In-house CISO | CISO as a Service | |
|---|---|---|---|
| Cost | Low, but hidden | High: salary, payroll taxes and benefits | Monthly and predictable |
| Start | Immediate | Months of recruiting | Right after signing |
| Independence | Low: reviews its own work | High | High |
| Experience | Limited to the current environment | Depends on the individual | Experience across many industries |
| Best for | Very early stage | Large enterprises | Small, mid-sized and growing companies |
The conflict of interest
When the same team that runs IT also assesses security, it is auditing its own work. There isn’t enough time or independence, and risks get pushed back behind the urgent tasks of the day.
How to get started
- Maturity assessment
An evaluation of the environment based on the NIST CSF 2.0 functions: govern, identify, protect, detect, respond and recover. - Prioritized plan
A roadmap with the highest-impact initiatives, the expected investment and targets agreed with the board. - Governance routines
A regular committee, clear indicators and executive reporting. - Continuous improvement
A new maturity measurement each cycle, showing progress in numbers.
Indicators a good CISO reports
- Maturity level for each NIST CSF function.
- Percentage of systems with up-to-date patches.
- MFA coverage on critical accounts.
- Results of phishing simulations.
- Time to detect and respond to incidents.
- Risks treated versus risks still open.
Checklist: does your company already have these?
- Someone formally responsible for security
- Security policy approved by the board
- Up-to-date risk map
- Incident response plan
- Security indicators reported to the board
- Ready answers for customer questionnaires
