Security Maturity Isn't About Having More Controls

Managing the right risks in the right way is what security maturity is all about.

Security Maturity Isn't About Having More Controls

One of the easiest ways to make a security program look mature is to add more controls.

More policies. More security tools. Another assessment. Another requirement in the control matrix. Another checkbox marked “implemented.”

Eventually, the organization can point to hundreds of controls and say, “Look how mature our security program is.”

But there is a problem with that measurement.

The number of controls an organization has tells us very little about how effectively it manages risk.

A mature security program isn't defined by how many controls exist.

It is defined by how deliberately the organization uses those controls to reduce meaningful business risk.

The Control Accumulation Problem

Security programs rarely become complicated all at once.

They accumulate. For example, a framework introduces a set of requirements; an auditor identifies a gap; a security incident results in a new procedure. Before long, a customer will ask for another control; a regulator will introduce another requirement. And then a security leader will purchase another tool to address yet another concern.

Over time, the organization develops layers of controls, processes, technologies, policies, and procedures.

Individually, most of them make sense, yet collectively, they can become difficult to understand.

Who owns this control?

What risk does it address?

How effective is it?

And perhaps the most important question: What risk are we actually reducing?

If we cannot answer those questions, adding another control probably isn't going to make the program more mature.

It may simply make it more complicated.

Maturity Is About Effectiveness

Consider two organizations.

Organization A has 400 documented security controls.

Most are manually tracked. Several overlap. Ownership is unclear for some. Testing is inconsistent. Metrics focus primarily on whether activities were completed.

Organization B has 150 controls.

Each has a defined owner, a documented purpose, measurable effectiveness criteria, and a clear relationship to identified business risks. Exceptions are understood and managed. Control performance is reported in a way leadership can use to make decisions.

Which organization has the more mature security program?

The answer shouldn't depend on the number 400 versus 150.

Organization B may be substantially more mature.

Because maturity isn't about the volume of security activity.

It's about the organization's ability to consistently understand, manage, measure, and improve risk.

My Take on Controls

A useful way to evaluate security maturity is to stop viewing controls as the destination.

Instead, think of the relationship as a chain:

Control → Effectiveness → Risk Reduction → Business Outcome

A control exists for a reason.

If we cannot explain what that reason is, we have a problem.

If we cannot determine whether the control is operating effectively, we have another problem.

If the control is effective but doesn't materially reduce an important risk, we have yet another problem.

And if we cannot connect the reduction of risk to something the business actually cares about, we may be measuring security activity rather than business value.

This is where mature security leadership differs from control administration.

The objective isn't to operate the largest possible control environment.

The objective is to operate an effective control environment that is proportionate to the organization's risks.

The Four Stages of Control Maturity

I find it useful to think about security maturity as a progression.

1. Existence

Do we have the control?

This is the most basic question.

We have policies and processes that are documented. We have the technology and we have evidence. This is important, particularly for establishing a security foundation, but it tells us very little about effectiveness.

2. Consistency

Is the control operating as intended?

The organization moves beyond simply having controls and begins establishing repeatable processes.

Ownership becomes clearer. The processes become standardized, and exceptions are documented. We have evidence that is consistently generated.

This is where the program begins becoming dependable.

3. Measurement

Do we know whether the control is actually working?

Now the organization starts measuring outcomes rather than simply activities.

Instead of asking: Did we perform the access review?

We begin asking: Did the access review identify inappropriate access, and was that access remediated within an acceptable timeframe?

That is a fundamentally different question. One question measures completion.

The other question measures effectiveness.

4. Risk Optimization

Are we investing the right amount of effort in the right controls?

This is where I believe that mature security programs begin to operate differently.

Not every risk deserves the same level of investment.

Not every control needs to be equally rigorous.

Not every security improvement requires another technology purchase.

The organization begins making deliberate decisions based on risk, business impact, regulatory obligations, threat exposure, and available resources.

At this stage, security becomes less about doing more and more about doing what matters most.

The Maturity Test

Here's a simple test I would encourage security leaders and GRC teams to apply to their control environments.

Take any significant control and ask five questions:

1. What risk does this control address?

If nobody can answer, question why the control exists.

2. Who owns it?

A control without clear accountability is difficult to manage effectively.

3. How do we know it works?

Evidence that a process occurred isn't necessarily evidence that the control was effective.

4. What happens when it fails?

Mature programs understand exceptions, failures, compensating controls, and remediation.

5. What business outcome does it support?

The answer might be protecting sensitive information, maintaining operational resilience, meeting a contractual obligation, protecting revenue, supporting customer trust, or reducing regulatory exposure.

The exact outcome will vary. The important thing is that there is one.

The GRC Trap

There is a particular danger here for organizations heavily focused on compliance.

Frameworks such as ISO 27001, SOC 2, NIST, PCI DSS, and others provide valuable structures for managing security.

But frameworks are not the objective.

They are mechanisms for helping an organization establish and demonstrate disciplined risk management.

It is entirely possible to become extremely good at satisfying control requirements without becoming equally good at managing risk.

That distinction matters.

Compliance asks whether defined requirements are being met.

Security maturity asks whether the organization has developed the capability to understand and manage its risks effectively.

The two should reinforce each other. They should not be confused with each other.

What Mature Security Leadership Looks Like

A less mature security conversation often sounds like this: “We need another control.”

A more mature conversation sounds like: “What risk are we trying to reduce?”

The first question leads toward control accumulation. The second question leads toward risk management.

Knowing that distinction becomes increasingly important as organizations grow.

Resources are finite. Security teams are finite. Budgets are finite. Management attention is finite.

A mature security leader recognizes that every additional requirement carries a cost.

Controls require people to operate them.

Processes require people to maintain them.

Technologies require configuration and oversight.

Evidence must be collected.

Exceptions must be managed.

Audits must be supported.

Every layer of complexity has a carrying cost.

Security maturity therefore requires the discipline to say both “yes” and “no.”

Yes, when a control meaningfully addresses an important risk.

No, when another layer of complexity provides little additional value.

That is not reducing security. It is practicing security deliberately.

The Leadership Takeaway

The goal of a mature security program isn't to eliminate every conceivable risk.

That isn't realistic.

The goal is to understand the organization's most important risks, establish appropriate safeguards, measure whether those safeguards are effective, and make informed decisions about the risk that remains.

That's a very different objective from building the largest possible control library.

So perhaps the next time someone asks:

“How many security controls do we have?”

we should answer the question with another question:

“How much meaningful risk are those controls reducing?”

That is a much harder question.

It is also a much better measure of security maturity.
