In early-stage startups, At some point every founder runs into the same question.
It usually comes up when a customer asks for a questionnaire. Or when a deal slows down because of a security review, or when someone on the team says, “We should probably get SOC 2.”
In practice, this assumption breaks down quickly. Security does not behave like a static architecture that can be designed once and implemented cleanly. It behaves more like software, where the system needs to be built incrementally, tested under real conditions, and evolved as complexity increases.
A more effective mental model is the one engineers already use when building products:
First make it work. Then make it better.
The challenge most startups face is not a lack of tools or frameworks. It is the absence of a functioning system.
Many companies attempt to adopt elements of mature enterprise architectures such as centralized identity, endpoint detection, or compliance frameworks like SOC 2 without having the underlying operational foundation in place.
This leads to a pattern that is surprisingly consistent across early-stage environments:
The result is a system that appears complete on paper but fails under real conditions because it was never designed to operate as a system in the first place.
There’s a reason good engineers don’t start with scale.
You didn’t build your product by starting with scale, a perfect architecture, or something that was ready for enterprise from day one.
You started with something small that worked. It was probably messy and limited, but it worked, and more importantly, you understood it. You knew where it broke, how to fix it, and you could explain how it behaved under real conditions.
Security follows the same pattern. The only difference is that most teams forget to apply the same discipline.
If security is treated as a system rather than a checklist, the design approach changes fundamentally. Instead of aiming for completeness, the goal becomes establishing a minimum set of capabilities that can operate reliably and provide a foundation for future improvements.
At its core, a functioning security system requires a small number of basic controls. These are not advanced capabilities, they are the equivalent of getting a system to run locally before thinking about scale, performance, or resilience.
The shift from early-stage to growth-stage security is usually triggered by external pressure, customer reviews, enterprise deals, or compliance requirements.
When these pressures appear before a foundational system is in place, startups are forced into reactive implementations.
This typically results in:
In effect, complexity is added without increasing resilience.
Companies that establish a working system early respond differently. Because they already have ownership, access discipline, and visibility, they can extend their system in a controlled way, aligning new requirements with existing capabilities rather than layering on disconnected solutions.
This pattern is consistent with how large-scale systems evolve in practice.
Companies like LinkedIn and Uber did not begin with the distributed architectures or security models they operate today. Their systems were built incrementally, with functionality validated at each stage before additional complexity was introduced.
Security followed the same trajectory.
The advantage of this approach is not just reduced risk, but improved adaptability. Systems that are built iteratively are easier to extend, easier to reason about, and less prone to failure under changing conditions.
The question most teams start with is:
“What does a complete security program look like?”
A more useful question is:
“How much security is enough security for our stage?”
This shift changes how decisions are made. It prioritizes operability over completeness and ensures that every control introduced has a clear purpose within a working system.
Security is not a static architecture that can be designed once and implemented fully. It is a system that must be built, tested, and evolved over time, much like the products it is intended to protect.
The most effective approach follows a principle that is already deeply understood in engineering:
Once a system works, maturity becomes a natural extension rather than a forced transition.
First make it work. Then make it better.
