Warehouse theft continues to be a costly and disruptive issue for businesses across the logistics and distribution sector. From stolen inventory to damaged reputations and increased insurance premiums, the impact of weak security measures can be significant. While external break-ins are a threat, many incidents stem from internal lapses or process weaknesses that are entirely preventable.
In this guide, we’ll walk through seven of the most common weak spots we encounter in warehouse security audits – and what you can do to proactively address them. Whether you’re managing a regional distribution hub or a last-mile fulfilment centre, these insights will help you strengthen your defences and reduce your exposure to theft.

Why Warehouse Theft Happens – and Who’s Behind It
Internal vs External Theft
While external intrusions get more attention, internal theft is often the more persistent threat. This includes employees pocketing small items over time, falsifying shipment records, or collaborating with external contacts to remove goods undetected. Unlike forced entry, internal theft tends to be ongoing, subtle, and hard to trace unless processes are in place to detect irregularities.
External threats, on the other hand, typically involve break-ins through poorly secured doors, fences, or loading bays. These are often carried out by opportunists or organised criminal groups who target high-value goods or fuel supplies.
High-Value Targets in Warehouses
Some of the most commonly stolen items include consumer electronics, tools, branded goods, and pharmaceuticals. However, anything portable and in demand is at risk. In recent years, diesel theft has also spiked, with fuel tanks on-site or in lorries being a common target.
Common Patterns and Missed Warning Signs
Theft rarely starts with a major loss. It often begins with small, unnoticed items going missing. Over time, if undetected, it escalates. Common red flags include stock inconsistencies, unusual access patterns, missing delivery records, or staff being present in unauthorised zones.
7 Common Warehouse Security Weak Spots
1. Poor Perimeter Security
Your first line of defence is your perimeter – and it’s often one of the weakest. Gaps in fencing, broken gates, or unmonitored entrances provide easy access for intruders. In many sites, delivery entrances are left open during the day for convenience, with minimal oversight.
Securing the perimeter means more than just a fence. It involves layered protection: high-security fencing, gated access points, surveillance coverage, and deterrents such as signage and lighting. Bollards or barriers can also be used to restrict vehicle access out of hours.
2. Blind Spots in CCTV Coverage
Warehouses are dynamic environments with changing layouts. New shelving, temporary storage zones, or racking can easily block existing camera views. As a result, high-risk zones may be left unmonitored without anyone realising.
Regular audits of your CCTV security system are essential. Modern systems offer panoramic or fisheye lenses to cover wider areas, and AI-assisted monitoring can flag suspicious activity in real time. Footage should be stored securely and reviewed after any reported incident.
3. Lack of Access Control for Staff and Visitors
It’s common for warehouses to issue shared fobs or leave internal doors unlocked for convenience. But without individualised access control, there’s no way to track who accessed which zone and when. This makes investigations near-impossible and opens the door to internal theft.
The solution lies in issuing named credentials (e.g. keycards or mobile-based smart access control) and defining role-specific access zones. Visitors and contractors should be logged digitally and given time-limited access, with escorts where needed.
4. Unsecured Loading and Dispatch Areas
Loading bays are high-traffic zones and often the easiest point of entry for theft. Goods sit temporarily in staging areas, lorries are loaded and unloaded, and it’s easy for unauthorised persons to blend in or remove items unnoticed.
These areas should be under constant surveillance, with clearly defined procedures for checking goods in and out. Restrict access to authorised personnel, and ensure all vehicle movements are logged. If possible, use vehicle recognition systems or delivery management software.
5. No After-Hours Monitoring
Criminals often strike when a site is unstaffed – overnight, during weekends, or bank holidays. If your site has no monitoring during these periods, it’s an open invitation.
Even small warehouses can benefit from 24/7 remote monitoring. Alarm systems linked to security cameras can alert off-site teams in real time, allowing for rapid response. Out-of-hours patrols or on-call guards can further reduce risk.
6. Poor Lighting Around the Facility
Dimly lit yards, walkways, or entrances make it easier for intruders to move undetected. It also increases the risk of accidents and makes staff feel less safe.
Motion-triggered lighting and dusk-to-dawn floodlights are both practical upgrades that deter trespassing. Lighting should cover entrances, perimeter fences, parking areas, and anywhere staff operate during darker hours.
7. Weak Internal Security Culture
Even the best systems fail if people don’t take security seriously. A culture of complacency or “it’s not my job” can allow internal theft to thrive and external breaches to go unreported.
Build awareness through training, onboarding, and regular briefings. Make it easy for staff to report suspicious activity anonymously. Recognition and accountability go a long way in creating a culture where security is everyone’s responsibility.
How to Conduct a Security Audit of Your Warehouse
If you haven’t assessed your security setup in the last 12 months, it’s time. A proper audit starts with a walkthrough of the site, noting access points, CCTV blind spots, lighting gaps, and zones with poor access control. Involve both security teams and warehouse managers to identify operational blind spots.
Check your logs: Who has access? When are deliveries unmonitored? Are procedures actually followed? A fresh pair of eyes, whether internal or via an external provider, can often spot vulnerabilities you’ve normalised.
The Business Case for Investing in Better Security
Every year, millions are lost in warehousing due to theft, downtime, and loss of client trust. For many, the cost of a basic security upgrade is far less than the cost of a single incident. Better systems also make insurance claims easier and may even reduce premiums.
Clients and supply chain partners are increasingly asking what measures are in place to secure their goods. A well-secured site gives confidence and supports stronger commercial relationships.
