Founders, Build Security Early
Every founder I work with has the same blind spot.
They're building a product. They're hiring. They're selling. They're raising. All the while, security sits somewhere on a future roadmap, filed under "we'll handle that when we're bigger."
Then a customer sends a 200-question security questionnaire. Or a lead investor asks for the company's SOC 2 status. Or an employee clicks the wrong link and the business stops for three weeks.
I've watched this play out in biotech, edtech, healthcare tech, data analytics, industrial manufacturing, and private equity portfolios. The pattern doesn't change. Founders who treat security as a future problem pay twice: once to catch up, and again to rebuild the customer trust they lost in the gap.
The founders who win treat security the way they treat finance, legal, and sales. As a function that starts small, grows with the business, and pays for itself in revenue, retention, and valuation.
The Fundamentals Haven't Changed
Building a successful company still comes down to a handful of durable principles. You solve a real problem for a real customer. You price it so the math works. You hire people who care about the mission. You protect what you're building from the things that can kill it. That last principle is where security lives. And the data on what happens to small companies who ignore it is ugly.
Recent small business cybersecurity research found that 61% of small businesses experienced a breach in the past year and 79% experienced at least one attack in the past five years.

The cost is real too. IBM's 2025 Cost of a Data Breach Report pegs the global average at $4.44 million per breach, with the U.S. average climbing to $10.22 million. Phishing was the most common initial attack vector. Third-party and supply chain compromise accounted for 15% of breaches.

If you're a founder, those numbers describe your customers, your vendors, and the acquisition targets your investors are eyeing. You don't get to opt out of that risk. You get to decide whether you manage it or inherit it.
Security Enables Growth. Full Stop.
I spent years inside a Fortune 500 retailer building a PCI compliance program. I've run GRC functions. I've delivered State of Risk reports to boards. The thing that surprised executives wasn't the threat data. It was how directly security tied to revenue.
Here's what that looks like in practice.
I worked with a tech portfolio company whose competitors didn't have SOC 2. Sales cycles either slowed or stopped entirely because prospects couldn't get past procurement. So they opted to pursue their own SOC 2 Type II. Once they earned the report, marketing had a trust signal for the website, sales had an answer to every security questionnaire, and customer success had a retention story. Their PE investors had a portfolio asset that was suddenly more attractive to downstream acquirers. That one investment moved three levers at once. Deal velocity. Customer retention. Exit multiple.
That's a business success story with security as the engine.
Your security program should do the same. It should shorten your sales cycle, unlock enterprise customers, reduce your insurance premiums, and raise your valuation. If it isn't doing those things, you've built compliance theater, not a security function.
When to Start: Pre-Seed, Seed, and Series A
The honest answer is: the day you incorporate. The practical answer depends on where you are.
Pre-seed and idea stage. You probably have two cofounders, a prototype, and a shared Google Drive. Your security work isn't a program. It's a set of habits. Turn on multi-factor authentication on every account. Use a password manager. Encrypt your laptops. Don't email source code. Write down how you'll handle customer data before you have customers. That's it. Thirty minutes a week. No budget required.
Seed and first ten employees. This is where most founders struggle. You're hiring, onboarding, and shipping. Security gets handed to whoever has the most patience for it, usually a technical cofounder who already has a full job. The result is a patchwork of good intentions with gaps you can't see. This is where you bring in your first fractional security leader. You don't need forty hours a week. You need four to eight hours a week of someone who's built programs before, who can prioritize the work, and who can translate what you're doing into language your customers, investors, and future auditors will understand.
Series A and product-market fit. You have paying customers. You have contractual obligations. You might have your first compliance requirement. Your fractional leader's scope grows. You start layering in managed security services to handle the work that needs to happen around the clock, like endpoint detection, log monitoring, and email security. You begin preparing for SOC 2, ISO 27001, HIPAA, or whatever framework your market demands. You build an incident response plan and test it.
By the time you raise a Series B, your security function should look like a small, capable team with clear executive ownership. Not a full internal department. A strategic leader plus the right outsourced partners.
That's how you signal trust to your future customers. That's how you accelerate sales cycles, increase revenue, and grow at the pace you want to grow.
The Case for Fractional Security Leadership
Hiring a full-time CISO is a six-figure commitment most early-stage companies can't justify.
Robert Half's 2026 projections put entry-level CISO salaries at $191,500 and senior CISOs at $278,250. IANS research pegs total CISO compensation between $250,000 and $700,000 annually. Even if you have the budget, there's a supply problem. The national cybersecurity workforce gap exceeds 225,000 unfilled roles.

A fractional CISO, sometimes called a virtual CISO or vCISO, solves both problems. You get executive-level leadership at a fraction of the cost, without the recruiting timeline. The fractional CISO market reflects the demand. It's projected to grow from $2 billion in 2025 to $7 billion by 2033, at a 15% compound annual growth rate.
Here's what a fractional CISO actually does for an early-stage company.
They write your first security policy set in language your team will actually read. They build your risk register and keep it current. They sit in customer security reviews so your founders don't have to. They prepare you for SOC 2 or ISO 27001 without selling you an expensive audit you aren't ready for. They run your tabletop exercises. They brief your board in business terms. When you hire a full-time security leader down the road, they onboard that person and hand off a working program.
The right fractional leader tells you what not to buy. I've talked plenty of founders out of expensive tools they didn't need. That's part of the job.
The Case for Managed Security Services
Fractional leadership handles strategy, governance, and executive communication. Managed security services handle the operational work that happens every hour of every day.
A good managed security services provider, or MSSP, gives you detection and response coverage you can't staff yourself. Endpoint protection. Log aggregation and SIEM monitoring. Email filtering. Vulnerability scanning. Phishing simulation. Twenty-four-seven alerting when something's actually wrong.
You're not paying for tools. You're paying for analysts who watch the tools and tell you when to act.
The fractional-plus-MSSP model is what most of the startups I advise land on. The fractional CISO sets direction, manages the MSSP relationship, translates alerts into business impact, and keeps your program audit-ready. The MSSP keeps the lights on. Together they cost a fraction of a single full-time security hire, and they cover ground one person never could.
Your job as a founder isn't to run a security team. It's to make sure one exists.
How to Proceed
If you're a founder reading this and your security program is currently the back of a napkin, here's a ninety-day starting point.
First thirty days. Write down every type of data you handle and where it lives. List your top ten vendors and what access they have. Turn on MFA everywhere. Pick a password manager and require everyone to use it. Draft a one-page acceptable use policy. Hire a fractional CISO for four to eight hours a week.
Next thirty days. Run a lightweight risk assessment with your fractional leader. Prioritize three to five controls that address your biggest risks. Stand up endpoint detection through an MSSP. Turn on logging across your cloud environments. Train your team on phishing, credential handling, and how to report incidents.
Final thirty days. Build your incident response runbook. Run a tabletop exercise with your leadership team. Identify which compliance framework matches your market and map a path to readiness. Put security on your board agenda as a standing item.
After ninety days, you'll have a program. It may not be a perfect one, but it will be a real one, complete with an executive owner, operational coverage, and a roadmap the next phase of growth will actually survive.
The Founder's Choice
Every founder I've worked with who got security wrong tells me the same things in hindsight. They wish they'd started earlier. They wish they'd hired a fractional leader sooner. They wish they'd stopped treating security as an expense and started treating it as the foundation their growth was built on.
The founders who got it right tell me something different. They tell me their security posture helped them close a marquee customer, pass a PE diligence review, win a partnership, or raise at a better multiple.
Security isn't about security. It's about business resilience. And business resilience is what separates the companies that scale from the ones that get written up as cautionary tales.
Start now. Start small. Get help.
