The phrase “Security by Obscurity” has a curious way of dividing a room. Say it in a gathering of software developers or cybersecurity professionals, and you’ll see heads nodding in approval alongside skeptical smirks. Some view it as a clever, low-cost tactic; others dismiss it as the digital equivalent of hiding a spare key under the welcome mat.
As James Thornton, a seasoned digital strategist, points out, both extremes miss the point. The reality is far more nuanced — obscurity is neither the magic shield that will save you nor the useless relic some claim it to be. Instead, it’s a subtle tactic that can still serve a valuable role in modern business security, but only when used with precision and perspective.
The Allure — and the Trap — of Obscurity
In business, speed is often prized over perfection. A growing company might not have the budget for a full-time security team or a sophisticated monitoring system. In those cases, simple tricks — like renaming an admin login from “/admin” to a random string or shifting a default port to a less obvious number — can make a tangible difference.
It’s easy to understand the appeal. If attackers can’t find the front door, they can’t try to pick the lock. But this is also where the danger creeps in. Once that hidden door is found — and it often is — all the protection it seemed to offer evaporates. Without strong encryption, authentication, and regular system audits, obscurity alone becomes a very fragile shield.
James Thornton captures this balance well in his in-depth breakdown on applying Security by Obscurity. His core advice is clear: treat obscurity as a layer of security, not the entire structure.
Why It Still Matters for Businesses in 2025
While obscurity isn’t the answer to all threats, it remains relevant in today’s corporate landscape — particularly for businesses that handle sensitive data but operate with lean resources.
- It Buys Time – A concealed entry point can slow down automated attacks, giving defenders precious minutes or hours to detect and respond.
- It Reduces Noise – By hiding common targets, you reduce the sheer volume of bot-driven intrusion attempts. This makes real threats easier to spot in your logs.
- It Protects Brand Confidence – Every minute an attacker spends fumbling is a minute your business avoids headlines about data breaches and lost trust.
I’ve seen small teams extend their incident response window simply by implementing a few clever concealment measures. It’s not a replacement for strong defenses, but it’s a helpful buffer in the chaos of real-world cyber threats.
When Obscurity Becomes a Liability
The trouble begins when leaders start to believe that obscurity is a complete defense. If the hidden door is weakly protected, it won’t matter how well it’s hidden. Worse, a false sense of security can lead to dangerous neglect — patches get delayed, monitoring becomes lax, and risks multiply quietly in the background.
Security history is filled with examples of this overconfidence. In one case, a company hid its internal admin portal behind a cryptic URL but didn’t enforce two-factor authentication. It took a determined attacker less than an hour to discover the URL through a public code repository — and from there, the system fell quickly.
Practical Applications in the Real World
For companies willing to use obscurity the right way, here are some tactics that can enhance overall security without breeding complacency:
| Obscurity Tactic | Business Benefit | Why It Works Only With Other Defenses |
| Masking system details in public-facing environments | Reduces automated scanning and opportunistic attacks | Skilled attackers can still uncover hidden details |
| Shifting default service ports | Cuts bot-driven intrusion attempts | No defense against targeted intrusion |
| Concealing internal infrastructure maps | Protects strategic design insights | Social engineering can still expose them |
| Obfuscating sensitive code segments | Slows reverse engineering | Weak encryption still leaves vulnerabilities |
Each of these measures acts as a speed bump for attackers, not a locked gate. On its own, a speed bump won’t stop a determined intruder — but in combination with reinforced doors, alarms, and patrols, it makes their job much harder.
The Psychology of Concealment
From a human perspective, there’s an undeniable satisfaction in knowing something others don’t. For executives, adopting a measure that seems to instantly reduce attack attempts can feel like a win. And it is — at least at first.
The real test comes over time. Attackers learn, adapt, and share information. What’s hidden today may be common knowledge tomorrow. In that sense, obscurity isn’t a one-time setup — it requires regular updates, just like passwords and software patches.
The Balanced Approach for 2025
Modern cybersecurity is built on layers. Strong encryption, robust authentication, real-time monitoring, and well-trained staff form the bedrock. Obscurity, used correctly, can be a useful top layer — a subtle extra that makes an attacker’s reconnaissance process slower and more expensive.
As Thornton notes, the key is not to overestimate its power. Just as camouflage can help a soldier in the field but won’t stop a bullet, obscurity can reduce exposure without eliminating risk.
Why Business Leaders Should Pay Attention
Many executives hand off security decisions to their IT departments, assuming it’s “too technical” for the boardroom. But obscurity as a strategy has clear business implications:
- Risk Management – Understanding its limits helps avoid costly breaches.
- Resource Allocation – Knowing when and how to implement obscurity ensures time and money are spent wisely.
- Reputation Protection – Public trust hinges on preventing incidents, and obscurity can help buy time to stop them.

Final Word: A Curtain, Not a Wall
In the end, security by obscurity is best understood as a curtain — one that hides what’s behind it from casual observers. But just like in the physical world, the curtain isn’t the lock, the alarm, or the reinforced steel door.
The businesses that thrive in 2025 will be those that understand this distinction and apply obscurity strategically. Not as a crutch, not as a shortcut — but as one thoughtful element in a broader, well-built security posture.
Because in cybersecurity, the goal is never to hide forever. It’s to stay ahead. And when obscurity is used with intention, it just might give you the head start you need.
