What is security debt? Is your org under it?

It’s about time that we talk about security debt. Security debt is what happens when you repeatedly put off necessary security updates, fixes, or enhancements because your priority is convenience or speed over solid security practices.

It sounds like a big deal, right? Well, it's because it is. 2024 is when cyberattacks become more frequent and more sophisticated. And then add to that the rising cost of breaches. Ignoring your security debt is a financial disaster waiting to happen.

If your organization has accumulated security debt, you’re facing higher risks of breaches, compliance headaches, and reputation hits that can take years to recover from. And here’s a gut-check question: Can you afford to delay another patch or update, considering how bad the implications of an attack have become?

Common Causes of Security Debt in Organizations

Here’s where most organizations get it wrong and rack up security debt faster than you can say breach. Let’s get straight into it. If you see yourself in any of these scenarios, it’s time for a serious course correction.

Rushing product development without security checks

Everyone wants to be first to market with their shiny new features, but skipping security in the race to launch is a huge mistake. Every time you push a feature live without a proper security review, you’re adding to your debt. It’s tempting to take shortcuts for speed, but those shortcuts skip where the vulnerabilities hide, and they’ll catch up with you sooner or later.

Relying on legacy systems that are outdated

Still running critical processes on old software? You’re not alone, but that doesn’t make it less dangerous. Legacy systems are a magnet for attackers because they usually have known vulnerabilities that haven’t been patched. Plus, they rarely integrate well with modern security tools that makes it even harder to protect them.

Not investing in ongoing security training for your teams

Your development teams are cranking out code every day, but how often are they getting trained on secure coding practices? If they’re not up to date on the latest threats, they’re likely introducing security flaws without even knowing it. Regular training on secure coding and threat modeling is a must-have if you want to avoid piling up security debt.

Falling behind on compliance requirements

Regulations like GDPR and HIPAA are not standing still. They evolve, and so should your compliance measures. Are you keeping up? Because if you’re not, then you’re risking more than fines. You’re also accumulating debt in the form of unaddressed requirements. The longer you delay compliance updates, the harder and more expensive it gets to catch up. 

Ignoring regular security audits

Skipping audits or conducting them only when absolutely necessary might save you time today, but it will cost you big when an issue finally shows up. Regular security audits help you find and address problems early before they grow into major liabilities. 

Overlooking third-party risks

Relying on third-party vendors and integrations can be a game changer for efficiency, but they’re also a big source of potential issues. If you’re not thoroughly vetting the security practices of your partners, you’re taking on their risks too. Every unvetted connection is a new entry point for attackers.

Inconsistent patch management

Patch management is one of those things everyone knows they should be doing but often gets pushed down the priority list. When you don’t patch regularly, you’re leaving known vulnerabilities wide open for exploitation. This is one of the fastest ways to accumulate security debt, and it’s easily avoidable with a disciplined update schedule.

The Risks of Accumulating Security Debt

It’s both risky and reckless to let security debt pile up. Here’s why you should be worried about every bit of security debt you’ve let slide:

  1. You’re an easy target for cyber attacks: Cybercriminals love low-hanging fruit, and security debt is exactly that. When you have unpatched vulnerabilities, outdated systems, and postponed updates, you’re practically inviting in the attackers. Your defenses have gaps, and the attackers know where to look to find them. You wouldn’t want to be the easy pick. Fix those gaps before someone else exploits them.
  1. The financial and legal blow could sink you: The average cost of a data breach hit $4.45 million last year, and I’m sure that it's now much higher than than. That’s a huge amount of money. But it doesn’t stop there, regulators are now more stringent than ever. Non-compliance can cost you big in fines and legal fees, not to mention the damage to your reputation. If you’re not up to date on compliance, you’re setting yourself up for a financial nightmare.
  1. Operational chaos when you’re reacting instead of planning: Ignoring security debt practically guarantees that a crisis will happen within your organization. Instead of making proactive fixes, you’ll end up trying to solve an issue when things go wrong. And trust me, they will go wrong. Reactive fixes take more time and more resources, and they disrupt your entire operation. It’s an expensive and stressful way to do business.
  1. Loss of customer trust and business reputation: If your customers find out you’ve been careless with their data, good luck keeping them. People want to trust that their personal information is safe, and a security incident destroys that trust. It’s hard to win customers back once they’ve lost faith in your ability to protect their data. One breach can undo years of brand loyalty.
  1. It slows down innovation and growth: Security debt will drag your entire business operation down. Instead of focusing on building new features or entering new markets, your team will be stuck dealing with security issues that should have been handled ages ago. The more debt you accumulate, the harder it gets to innovate without risking serious vulnerabilities.
  1. Your insurance premiums are going to skyrocket: Think your cyber insurance will bail you out? Not so fast. Insurance providers are catching on to companies that let security debt slide, and they’re adjusting their premiums accordingly. If your security posture is weak, expect to pay a lot more. Or worse, find yourself uninsurable altogether.

How to Spot Security Debt Before It Takes Down Your Business

You can’t fix what you can’t see, right? If you want to get serious about clearing up your security debt, you need to know where it’s hiding. Here’s how to pinpoint those gaps before they become massive liabilities:

Step 1: Start with regular security audits

Don’t wait for a breach to find out where your weaknesses are. Conducting security audits regularly is the fastest way to get a handle on your current security posture. Audits help you see what’s outdated, what’s vulnerable, and where you’ve let things slip. Make it a non-negotiable part of your routine.

Step 2: Integrate continuous threat modeling

As we all know, threat modeling is not a one-and-done task. It should be a continuous process throughout the entire Software Development Life Cycle (SDLC). Doing this early can help you catch potential issues before they turn into serious risks. This way, you’re always one step ahead of the attackers. If you’re not doing this yet, start now. Your future self will thank you.

Step 3: Take advantage of  security architecture reviews

Security architecture is the skeleton of your organization’s defenses. If it’s weak, everything else falls apart. Regular reviews of your security architecture will help you find any cracks where vulnerabilities can slip through. You need to know if your controls are still effective or if they need an overhaul. This is your chance to fix structural problems before they become catastrophic.

Step 4: Track vulnerability management metrics

If you’re not measuring your vulnerability management, then expect a disaster to happen sooner rather than later. Keep track of how many vulnerabilities you’ve identified, how many are unpatched, and how long it’s taking to address them. These metrics will give you a clear view of where security debt is accumulating. The longer those issues go unresolved, the deeper the debt.

Step 5: Analyze incident response data

Every time you respond to a security incident, you’re gathering valuable data. Look for patterns. Repeated issues are a huge red flag for underlying security debt. If you’re constantly dealing with similar breaches or attacks, it’s a sign you’ve got unresolved problems that need attention.

Step 6: Assess your security tooling regularly

Just because you have a tool in place doesn’t mean it’s doing its job effectively. Regularly evaluate the tools you’re using and whether they’re still meeting your needs. Outdated or underperforming tools contribute to security debt because they give you a false sense of protection.

Strategies to Reduce and Manage Security Debt

You’ve identified the problem, now it’s time to work on it head-on. If you’re ready to stop ignoring security debt and start eliminating it, here’s what you need to do:

Invest in ongoing security training for your teams

Your developers are the first line of defense against security issues. If they’re not up to date with secure coding practices, you’re in trouble. Make ongoing training a priority. Whether it’s secure coding, threat modeling, or the latest in cloud security, regular updates keep your teams sharp and proactive. This isn’t just a one-time thing, it needs to be part of your culture.

Adopt a proactive security approach across all projects

Stop waiting for problems to surface before you fix them. Integrate security into every stage of your product development. Continuous monitoring, automated vulnerability scans, and regular risk assessments should be standard. The goal is to catch issues early before they can snowball into serious problems. Reactive fixes are expensive and disruptive, proactive ones aren’t.

Upgrade and modernize your legacy systems

If you’re still relying on outdated software and systems, you’re asking for trouble. Legacy infrastructure is full of holes that hackers know how to exploit. It’s time to invest in modern, secure, and compliant environments. Migrating away from legacy systems is an important part of reducing your security debt.

Establish a strong patch management process

One of the easiest ways to manage security debt is by staying on top of updates and patches. Set a clear and disciplined process for rolling out patches as soon as they become available. Delayed updates are a major cause of accumulating debt. If you don’t have a patch management plan in place, make it a top priority today. Not tomorrow.

Use automation for vulnerability management

Manual vulnerability tracking can’t keep up with how fast today’s development cycles have become. Automate wherever you can, whether it’s for scanning, testing, or deploying fixes. Automated tools can spot issues faster and with fewer errors to help you keep your security posture strong without weighing down your teams.

Prioritize risk-based remediation

Not all issues are created equal. Some vulnerabilities need immediate attention, while others can be scheduled for later. Use a risk-based approach to prioritize fixes. Focus on the high-impact, high-risk issues first. This way, you’re using your resources efficiently and taking on the biggest threats before they become bigger problems.

Regularly review and update your security policies

Policies are only effective if they’re current. Make it a habit to review your security policies regularly, especially after a significant update or a security incident. Are they still aligned with best practices? Are there gaps you need to address? Keep them relevant, clear, and enforced across the organization.

Is Your Organization Under Security Debt?

It’s time to be brutally honest with yourself: Have you been putting off critical security fixes? Have you skipped out on updates, audits, or regular training because there wasn’t enough time or budget? If so, your organization is likely carrying significant security debt, and it’s only a matter of time before it catches up with you.
