# [Secure by Design: Why New Infrastructure Demands More than Off-the-Shelf Locks](https://blog.contoursecure.co.uk/blog/secure-by-design-why-new-infrastructure-demands-more-than-off-the-shelf-locks)

When planning new infrastructure, it’s tempting to default to “standard” components. For many, locks are treated as commodity hardware chosen based on price and availability rather than long-term performance.

But in today’s world, where vandalism, tampering, and service disruption are all on the rise, off-the-shelf cam locks no longer meet the demands of modern infrastructure projects. A secure-by-design approach is needed, one that builds resilience into every stage of the specification process.

 

#### The Risks of Off-the-shelf Locks

Legacy lock designs like pin hex, square head, or tri-head were never built for high-risk, public-facing environments. When used in new infrastructure projects, they introduce vulnerabilities from day one. Common issues include:

- **Susceptibility to tampering** with everyday tools such as screwdrivers or pliers.
- **No compression technology**, leaving enclosures prone to rattling or forced entry.
- **Empty spaces and protrusions** that provide leverage points.
- **Limited durability** under repeated use or environmental conditions.

Choosing these locks at the specification stage may appear cost-effective, but the real price comes later in the form of vandalism-related repairs, cabinet replacements, and service downtime.

#### Why Secure-by-design Matters

Secure-by-design means thinking about resilience not as an afterthought, but as a core design principle. For enclosures, that means recognising the lock as the frontline of security and specifying tamper-resistant designs from the outset.

Benefits include:

- **Reduced lifetime costs** by avoiding early replacements or expensive callouts.
- **Increased resilience** to tampering and forced entry.
- **Extended service uptime** by protecting the systems inside cabinets.
- **Better alignment with public safety priorities**, where reliable security is no longer optional.

 

#### What Tamper-resistant Locks Add to New Projects

Specifying tamper-resistant locks from the start allows new infrastructure to deliver lasting value. Key engineering features include:

- **Three-point contact opening** to resist manipulation.
- **Compression mechanism** for a tighter, more durable seal.
- **Smooth, low-profile surfaces** with no leverage points.
- **Restricted key inserts** to minimise unauthorised access.
- **Compatibility with standard footprints**, giving flexibility for future retrofits or replacements.

This combination helps ensure that new cabinets, feeder pillars, telecom enclosures, and transport infrastructure are equipped to withstand the realities of their environment.

 

#### Building Resilience Starts at Specification

Off-the-shelf locks may seem convenient, but in public-facing infrastructure, they create vulnerabilities that can cost far more in the long run. By choosing tamper-resistant cam locks from the design stage, you’re investing in resilience, service continuity, and public trust.

Whether you’re specifying new builds or planning upgrades, secure-by-design decisions protect infrastructure for years to come.
