For a startup operating on a limited runway, a breach is an existential threat.

Four in five small businesses are hit by breaches, and the consequence of a security incident hits them much harder.

Five-person team PhoneMondo, for example, saw 10.5 million records stolen in a January 2025 breach. That’s on par with the losses that airline giant Qantas suffered a breach in 2025 in which it lost 11 million customer records being leaked online.

Despite what’s at stake, many startups rely on default security configurations and shared credentials to keep operations moving. These practices, however, become ingrained patterns that are harder and more costly to change as you scale. 

Why startups are prime targets for breaches 

Attackers may reap significant rewards by targeting bigger firms, but breaching them takes more work and demands sustained effort, custom tooling, and patience.

Startups, on the other hand, have weaker defenses, and to attackers that represents lower effort and reasonable reward. They’re appealing targets because of:

  • Low-friction access: Cybersecurity for startups is often deprioritized in favor of product development. Many rely on default security configurations and weak security practices that can be quickly exploited.
  • High-value data: Startups handle high-value data from day one. Everything from customer emails and payment details to proprietary technology can be attractive targets for resale and theft.
  • Access to bigger targets: Startups often integrate with larger enterprise clients. A breach in your company could become an entry point into a bigger target, making your company a liability.

Security debt compounds faster than you think

Bad security culture compounds. For example, the habit of sharing admin passwords may be a pragmatic shortcut for a team of three. It becomes a glaring vulnerability for a team of 30.

This is security debt. The longer these weak practices remain, the harder and more costly they become to fix.

Security debt is an obvious red flag during due diligence. When clients work with you, they are entrusting you with their data, which also includes their customers’ data.

A breach on your end becomes a liability that puts them at risk of noncompliance and damages their reputation (that could be SOC 2 compliance, GDPR readiness, or HIPAA certification, depending on your industry).

Enterprise clients won’t sign on the dotted line without proof that you handle data securely.

Secure your startup with these first steps

Good security culture also compounds. Training a team on proper credential management from day one is far easier than forcing a culture shift at week 50.

By building security from the beginning, you make secure defaults the standard, which means fewer fires later and a smoother compliance and dealmaking journey.

Strong cybersecurity for startups doesn’t require massive budgets or sacrificing speed. You just need to make intentional decisions that establish secure security practices before bad habits take root.

Here’s where to focus first.

Secure your perimeter 

Your network perimeter is no longer defined by the walls of your office space. With hybrid and remote work now the norm, sensitive business traffic is routed through dozens of unsecured connections — from coworking spaces, cafes, home networks, and even on airplanes — exposing your business to a myriad of network security threats. 

Use a business VPN to secure a modern and distributed team. All team traffic is immediately encrypted, no matter where your team connects from. This prevents attackers from intercepting sensitive information such as credentials, customer data, and your intellectual property.

Secure your people 

Attackers don’t just target systems; they target people, too. And your team handles sensitive data every day. People prioritize convenience, which is why weak password practices are common — they stem from security fatigue. Protect your accounts with a team password manager and enable 2FA to make stolen credentials useless. 

Choosing an encrypted email solution with a custom email domain also protects sensitive communications from interception, keeping internal discussions secure and giving your team the confidence to share information freely. 

Secure your assets

Your company is built around IP, customer data, financial information, roadmaps. They’re also what attackers want most.

Adopting an end-to-end encrypted cloud storage to store your files guards them from unauthorized access. Pair that with granular access controls to ensure only the right people can access sensitive data, reducing risk if an account is compromised. 

Cybersecurity is not something you can afford to delay

Cybersecurity isn’t a problem reserved for enterprises. The data shows that smaller, fast-growing companies are breached every week — often through weak credentials, fragmented access controls, or inherited third-party risk.

The difference between startups that survive these incidents and those that don’t is rarely luck. It’s whether secure foundations were built early — before bad habits became systems and before clients began asking hard questions during due diligence.
