Many business owners delay software updates or keep using old systems to save costs or avoid downtime. It may feel like a harmless way to stretch your IT budget, but outdated software isn’t just an inconvenience – it’s a serious security and operational risk.
In fact, a recent survey found 41% of small businesses experienced a cyberattack in 2023, with a median incident cost of $8,300. A significant number of these attacks exploit known flaws in outdated software. One report revealed that 32% of cyberattacks start with an unpatched software vulnerability.
In other words, running obsolete, unpatched programs makes your company an easy target. And while it might seem harmless, the risks tell a different story.
Let’s take a closer look at why outdated software creates vulnerabilities, how it can quietly drain productivity, and what practical steps you can take to keep your business protected and efficient.
Skipping updates or holding on to legacy software might seem like a way to save money or avoid disruptions. Many business owners see upgrades as costly “nice-to-haves” and hope to get by with the status quo. However, this is a false economy – any short-term savings can be wiped out by the fallout from a security breach or system failure.
Hackers actively exploit known vulnerabilities in outdated software. In fact, outdated systems are considered “low-hanging fruit” for cybercriminals. One cybersecurity study found that organizations with poor patching practices (slow or inconsistent updates) were over seven times more likely to suffer a ransomware attack compared to those that promptly apply patches. In other words, failing to update software dramatically raises your risk profile, potentially inviting costly attacks.
From a financial perspective, deferring updates can backfire badly. The “savings” from avoiding an update or new software license pale in comparison to the costs of a data breach, downtime, or ransom payout.
A single incident can rack up expenses through emergency IT remediation, lost sales during outages, legal/regulatory fines, and reputation damage. As one IT expert put it, many small businesses treat security as a cost center until an outage or breach happens – not realizing the far greater losses those incidents can cause. In short, what looks like thrift today can turn into a huge expense tomorrow when outdated software is exploited.
When software reaches “end-of-life” (EOL) status, it means the vendor has stopped providing updates or security patches for it. Continuing to run EOL software is like leaving a door unlocked for intruders. Any new vulnerabilities will remain unfixed, and hackers know they can exploit those weaknesses at will.
Cybercriminals actually track which organizations are using outdated systems, because they make easy entry points. Automated scanning tools will probe the internet for servers running old versions of Windows, outdated VPN appliances, or unpatched applications, looking to penetrate them. Without updates, even minor bugs can be leveraged to gain unauthorized access or cause havoc.
History shows countless examples of attacks through outdated software. For example, in early 2021 a massive cyberattack struck Microsoft Exchange email servers worldwide. Attackers exploited several already-known (and even patched) vulnerabilities on unupdated Exchange servers, affecting over 30,000 U.S. businesses from small firms to local governments. Microsoft had released fixes, but companies that failed to install the updates remained vulnerable – and cybercriminals took full advantage.
Another warning came in 2023, when U.S. cybersecurity officials (CISA) issued an alert about hackers actively exploiting end-of-life SonicWall VPN appliances. Despite the known risks, thousands of organizations were still using these outdated VPN devices, which no longer received patches, and they quickly became targets for attackers.
Even large enterprises have learned this lesson the hard way. Back in 2017, the global NotPetya malware outbreak devastated companies like shipping giant Maersk and food manufacturer Mondelez. Mondelez later revealed that NotPetya spread into their network via outdated, unpatched software, causing major financial losses.
These cases illustrate a clear pattern: unsupported software becomes a magnet for breaches. If your business is running old versions of Windows, like the now-retired Windows 7 and 8 (soon to include Windows 10) or other EOL applications, it’s not a question of if attackers will attempt to exploit them – but when.
Security risks aside, sticking with outdated software can bog down your day-to-day operations. Old software often means old bugs and limitations that were fixed in later releases. You might notice frequent glitches, crashes, or slow performance that disrupt your employees’ work.
Incompatibilities can crop up, too – legacy systems may not integrate well with newer tools, cloud services, or even updated file formats, leading to errors and workflow headaches. All this results in lost productivity: time spent dealing with IT issues or working around constraints is time not spent serving customers or improving the business.
By hanging onto obsolete software, you’re also missing out on new features and efficiencies that modern systems provide, like streamlined workflows or automation capabilities that boost output.
There are also practical support and maintenance issues with legacy tech. Vendors typically discontinue support for EOL products – meaning if something breaks, you can’t call the manufacturer for help. You may be forced to hire expensive third-party consultants or implement clunky custom workarounds to keep things running. Those hidden maintenance costs can add up over time.
Meanwhile, the risk of a major failure increases. Outdated software running on aging hardware is more prone to crashes and downtime. Consider a real-world example: a manufacturing company once suffered a week-long production halt because their antiquated inventory software could not integrate with a new cloud-based system, causing a cascade of failures. This downtime cost the company millions in lost revenue and delayed orders – a huge price for not modernizing in time.
Even on a smaller scale, think about your own team’s morale: employees get frustrated having to wrestle with slow, unreliable programs or use tools that feel like relics. Over time, that frustration can sap morale and contribute to higher staff turnover or difficulty attracting talent. Modern businesses run on modern software for good reason – it’s generally more stable, better supported, and far more efficient.
Using outdated software isn’t just a technical issue; it can become a serious compliance and business continuity problem. Many industries have regulations that require companies to maintain up-to-date, secure systems to protect data. For instance, payment processing standards (PCI DSS) mandate using supported, secure software, and failing to comply can lead to heavy fines or even losing the ability to process credit cards.
Healthcare regulations like HIPAA demand robust protections for patient information, and relying on an EOL system lacking security updates could put an organization in violation – risking penalties and legal liability. Regulators and auditors are increasingly savvy about technology; they will flag unsupported software during audits. The fallout might include forced upgrades under tight deadlines, or worse, being barred from certain contracts or industry certifications until issues are fixed.
Outdated software can also jeopardize your business continuity. A cyber incident or prolonged outage stemming from legacy systems can cripple operations. Some businesses might never fully recover from a major data breach or ransomware attack. Beyond the immediate cleanup costs, you face reputational damage that can be hard to repair. Customers, partners, and the public may lose trust if they learn that a breach of their data was caused by neglecting basic security hygiene like software updates.
These days, news of a breach travels fast, and being labeled as “the company that didn’t patch its systems” is not a good look. Brand reputation is one of your most valuable assets, and it’s closely tied to customer confidence.
Unfortunately, a security incident caused by outdated software can make clients question whether your business is reliable and safe to work with. As some in the industry say, you can’t put a price on lost trust. Thus, staying current with software isn’t just an IT task – it’s essential to safeguarding your company’s good name and ensuring you can keep operations running smoothly even when facing adversity.
For small and midsize business owners, the goal is clear: don’t let outdated software be the weak link in your company’s defenses or productivity. Here are some actionable best practices to manage software lifecycles and updates strategically:
By following these practices, even a small business with limited IT resources can significantly reduce the risks associated with outdated software. The key is to be proactive: treat software updates and system upgrades as integral to your business strategy, not as ad-hoc chores.
Remember that cybersecurity and stability start with up-to-date software. As CISA succinctly puts it, the best defense against online attackers is to keep your software current and replace anything that’s end-of-life. Investing a bit of time and money now in modernizing your tech can save you from nightmarish scenarios down the road.
Outdated software might run “well enough” today, but it comes with hidden risks that no growing business can afford to ignore. Security vulnerabilities, compliance troubles, unreliable performance, and the threat of breaches are all amplified when your systems aren’t kept up to date. On the flip side, keeping your software modern and patched helps protect your company’s data, ensures smoother operations, and preserves your hard-earned reputation.
