Security problems in startups are like termites. By the time you see the damage, the infestation has been going on for months. Most founders discover their security gaps when a prospective customer sends a security questionnaire, or worse, when something actually goes wrong.
Here are five early warning signs that your startup has a security problem, and what to do about each one.
1. You have no idea who has access to what
Open your AWS console. Can you name every IAM user and explain why they have the permissions they do? Check your GitHub org. Are there former employees or contractors who still have access? Look at your SaaS tools. How many people have admin access to your CRM, your analytics platform, your payment processor?
If you cannot answer these questions in under five minutes, you have an access control problem. This is the number one security issue we find in early-stage startups. People are added to systems and never removed. Permissions are granted broadly because it is easier than figuring out the minimum required access.
Fix: Do an access audit today. It takes about two hours. List every system, every user, and their permission level. Remove anyone who should not be there. Then set a calendar reminder to do this quarterly.
2. Your secrets are in your code
Search your git history for strings like "password", "api_key", "secret", or "token". If you find credentials in committed code, even if they are in a branch that was never merged, they are compromised. Git history is forever, and anyone with repo access can find them.
This is more common than you would think. We have found production database passwords, Stripe API keys, and AWS root credentials in startup codebases. Once a secret is in git, rotating it is the only safe option.
Fix: Move all secrets to environment variables or a secrets manager (AWS Secrets Manager, HashiCorp Vault, or even a simple .env file that is gitignored). Install a pre-commit hook like gitleaks or trufflehog to prevent secrets from being committed in the future. Then rotate every credential that has ever been in your codebase.
3. You have no logging or monitoring
If your production application goes down right now, how would you know? If someone accessed your database and exported all customer records, would you have any evidence? If a developer pushed malicious code to production, could you trace it back?
Many startups have zero centralized logging. Application logs go to stdout and disappear. There are no access logs for critical systems. There is no alerting for suspicious activity. This means that if a security incident happens, you have no forensic trail to investigate.
Fix: At minimum, set up centralized logging for your application, your infrastructure, and your authentication system. Use a tool like Datadog, CloudWatch, or even a self-hosted ELK stack. Configure alerts for failed login attempts, privilege escalation, and unusual data access patterns. This does not have to be expensive or complex. A basic setup takes a day.
4. Nobody owns security
When you ask "who is responsible for security?" at your company, what happens? If the answer is "everyone" or "the engineering team" or a long pause, that means nobody owns it. Security without ownership is security without accountability, and security without accountability is no security at all.
Fix: Assign a security owner. At your stage, this does not need to be a full-time role. Pick someone on the engineering team who is interested and give them 10 to 20 percent of their time to focus on security. Give them a budget, even a small one, and clear objectives: implement SSO, run a vulnerability scan, set up logging. If nobody on the team is qualified, bring in a fractional CISO to set the foundation.
5. You have never tested your own defenses
When was the last time someone tried to break into your application? Not a real attacker, a deliberate security test. If the answer is "never," you do not know what your vulnerabilities are. You are relying on the assumption that your developers wrote secure code, which is a dangerous assumption.
Fix: Run a penetration test. For an early-stage startup, a basic web application pen test costs $5,000 to $15,000 and takes one to two weeks. The findings will give you a prioritized list of vulnerabilities to fix. Many are quick wins: missing security headers, open redirect vulnerabilities, insecure direct object references. Fix the critical and high findings immediately, then schedule annual retesting.
The bottom line
Security does not have to be expensive or time-consuming at the startup stage. But it does have to be intentional. Ignoring it until a customer forces the conversation puts you in a reactive position where everything is urgent and nothing is planned. Spend a week addressing these five areas and you will be ahead of 90% of startups at your stage.
Four more signs that surface once you start looking
The five above are the ones you can check in an afternoon. These take slightly longer to spot and cause just as much damage.
Nobody leaves cleanly. Pull your identity provider user list and compare it against your current payroll. If the two do not match, you have an offboarding problem, and offboarding is where access problems become breach problems. The account that gets missed is almost never the ex-employee's email, which someone remembers to kill. It is the AWS IAM user created for a one-off migration, the personal access token on a CI job, or the shared login for a monitoring tool that never went through SSO.
Nobody knows how old your dependencies are. Run your package manager's audit command right now. If the output scrolls, that is not automatically an emergency, but the absence of any number you can quote for how long a critical CVE stays unpatched is. Attackers do not need a clever zero-day when a known deserialization flaw in a two-year-old library is sitting in production. Set a patch target you can actually hit, write it down, and measure against it.
Your backups have never been restored. A backup that has not been restored is a hypothesis. Ransomware and a bad migration both end at the same question, which is whether you can rebuild from your last known good state and how long it takes. Pick a Tuesday, restore your production database into a scratch environment, and time it. Most teams discover the restore works and takes four hours longer than anybody assumed, which is exactly the kind of thing you want to learn on a Tuesday.
New vendors arrive by credit card. If an engineer can sign up for a tool, connect it to your production database with a read replica, and expense it without anyone reviewing what data it holds, your data perimeter is defined by whoever had a card handy. You do not need a heavyweight vendor risk program at your size. You need one rule: anything that touches customer data gets a second pair of eyes before it gets a credential.
What a security questionnaire exposes first
Most founders meet these problems through a buyer's questionnaire rather than an incident. The rows that fail are consistent, and they map almost exactly onto the signs above.
Do you perform periodic access reviews, and can you provide the most recent one? Do you have documented onboarding and termination procedures? Is MFA enforced for all administrative access? Do you retain audit logs, and for how long? Have you had a third-party penetration test in the last 12 months, and were the findings remediated? Do you have a documented incident response plan, and has it been tested?
Notice what those questions have in common. Each asks for an artifact, not an assertion. Answering yes without a dated record behind it is how a deal enters security review and stays there for six weeks. The cheapest possible preparation is to start producing those artifacts on a schedule now, so that when the questionnaire lands you attach files rather than write promises. Our free Workspace exists to hold that register, and you can use it whether or not you ever hire us.
How to triage when everything looks broken
Doing all of this at once is not realistic while you are also shipping product. Order the work by blast radius rather than by how bad the finding sounds.
First tier: anything that gives an outsider access to production or customer data with no further steps. A live credential in a public repository, an S3 bucket or database exposed to the internet, an admin panel with no authentication, MFA missing on the cloud root account. These get fixed today, not scheduled.
Second tier: anything that turns a small compromise into a large one. Overly broad IAM roles, no network separation between your application and your data store, a single shared admin account, secrets that cannot be rotated without downtime. These are a fortnight of engineering time and they change the shape of a bad day.
Third tier: everything that improves your ability to see and respond. Centralized logging with retention, alerting that a human actually receives, a written incident plan with names and phone numbers in it. This tier feels less urgent and is the one that determines whether you can answer "what did they access" when it matters.
A worked example from the pattern we see most often. A 25-person SaaS company finds a Stripe restricted key in git history, an IAM role with wildcard permissions used by every service, and no log retention beyond 7 days. Correct order: rotate the key and audit Stripe activity for the exposure window on day one, scope the IAM role down over the following two weeks with staging validation first, then extend log retention to a year. Doing the logging work first feels productive and leaves the live credential exposed for a fortnight.
The signs that are not actually problems
Plenty of early-stage teams get talked into spending on things that do not reduce their risk. Being honest about that is more useful than adding items to your list.
Not having a SIEM is fine at your size. Cloud-native logging with sensible alerts covers the same ground for a fraction of the cost and the operational burden. Not having a WAF is usually fine if your application validates input properly and you are not a common target. Not having formal policies is fine until a buyer or a framework asks, and generating 40 pages of policy you do not follow is worse than having none, because an auditor will sample against what you wrote.
Not having a penetration test is fine if you have not shipped to real customers yet. Test the thing that exists, not the thing you plan to build. When you do commission one, scope matters more than the price: a single small application starts from $1,000 with us, while a multi-tenant platform with a public API and several user roles costs several times that because the testing effort is genuinely larger. A cheap test against the wrong scope is money burned.
And you probably do not need us for most of this. Everything in this article is work a competent engineer can do with a week of protected time, and doing it in-house builds knowledge that outsourcing does not. The point where outside help earns its cost is narrow: a deal blocked on a framework with a date attached, an incident you cannot diagnose, or a regulated data type you have never handled. If that is where you are, tell us what the buyer asked for and we will be clear about which parts you should keep in-house. If it is not, run the list yourself and put the budget into product.
