In a nutshell
- 🔒 Security updates matter: unpatched devices expand your attack surface, and once they hit end‑of‑life (EOL), risk accumulates fast.
- 📅 Recommended cadences: smartphones and routers monthly (immediate for critical flaws), cameras monthly/bi‑monthly, TVs and speakers quarterly—paired with 4–7 year support windows.
- 🛠️ Enforce protection: enable automatic updates, check firmware versions monthly, subscribe to vendor security bulletins, and isolate legacy gear on a guest network.
- ♻️ When updates stop: replace high‑risk devices, reduce privileges for low‑risk ones, factory reset before recycling, and consider reputable community firmware cautiously.
- 🇬🇧 UK context: the PSTI regime requires a declared update period and better disclosures—use them to choose longer‑supported products and track support end dates.
Smart devices do not sit quietly on a shelf; they are always-on computers with an internet connection and a growing attack surface. From your router to your smart doorbell, each one runs code that can—and will—need fixing. Criminals move fast. So should your updates. In the UK, vendors must now declare how long they’ll provide security updates, but that still leaves a practical question: how often is enough? This guide lays out a clear cadence for different categories, shows how to check whether you’re protected, and explains what to do when support runs out. The safest policy is to plan for updates like you plan for insurance—routine, predictable, and non-negotiable.
Why Security Update Frequency Matters
A security update is not a cosmetic tweak; it is a repair to a live system exposed to the internet. The gap between a disclosed flaw and real-world exploitation can be days, sometimes hours. Routers and IP cameras are especially critical because they face the internet directly and can be hijacked into botnets or used as a beachhead into your home network. Leaving a connected device unpatched is like leaving a window cracked in winter—sooner or later, the weather finds it.
There is also the rhythm of vulnerability discovery to consider. High-value platforms, such as smartphones and major operating systems, see a constant stream of issues and publish monthly or even out-of-band patches. Lower-cost IoT gear may ship slower updates, but that does not make the risk smaller. In practice, the longer the gap, the bigger the batch of fixes, and the harder it is to validate changes. Short, frequent updates reduce blast radius and make rollbacks simple if something breaks.
Finally, consider end-of-life (EOL). Once a device stops receiving security fixes, you are accumulating risk every month it stays online. Attackers target abandoned products because signatures remain static and known exploits proliferate. If a device is out of support and handles sensitive data or controls access, plan to retire it.
Recommended Cadence by Device Type
Manufacturers vary widely, but you can set a baseline. The UK’s Product Security and Telecommunications Infrastructure (PSTI) regime requires vendors to declare a minimum support period, not a specific frequency. Treat the figures below as a practical, consumer-friendly target for a reasonable level of assurance, assuming normal household risk. Where your device stores or transmits video, audio, or credentials, aim for the tighter end of these ranges.
| Device | Update Cadence (recommended) | Support Window (minimum advisable) |
|---|---|---|
| Smartphones/Tablets | Monthly security patches | 5–7 years |
| Home Routers | Monthly; immediate for critical flaws | 5+ years |
| Smart TVs/Streaming Sticks | Quarterly; faster if app store issues arise | 5 years |
| Security Cameras/Doorbells | Monthly or bi‑monthly | 4–5 years |
| Smart Speakers/Displays | Quarterly | 4 years |
| Wearables | Monthly or quarterly | 4–5 years |
| Thermostats/Lighting/Hubs | Quarterly; immediate for critical fixes | 5 years |
These figures balance practicality with risk. Devices that control access (locks, alarms), process video/audio, or sit at the network edge merit faster cadences. Always enable automatic updates where available and prefer vendors that publish a clear, time-bound security support policy. When shopping, look for the declared support period on packaging or the product page, and prioritise brands with a public vulnerability disclosure programme. That transparency signals mature security practice, which often correlates with timely patches.
How to Check and Enforce Updates
Start with the basics. In settings, toggle on automatic updates for both the device firmware and its companion apps. Some products install patches silently overnight; others require a tap to confirm. Schedule a monthly “patch hour” where you trigger manual checks on your router, cameras, and hub—then power cycle devices that need a reboot. For routers, log into the admin page, look for “Firmware” or “Software,” and note the installed version and release date.
Next, verify that your vendor communicates. Subscribe to security advisories or product newsletters. Many reputable brands maintain a security bulletin page with CVE references, versions, and dates; set a calendar reminder to skim it quarterly. On phones and tablets, keep the OS and app store clients up to date—outdated app managers can silently block new patches. Where possible, join beta channels only on secondary devices; pre-release software can delay stable security fixes.
Network hygiene helps. Place untrusted or legacy gadgets on a guest network or VLAN with limited access to your main devices. Disable remote access features you do not use. If a device requires port forwarding, document why and revisit it after each update. Strong, unique passwords and multi-factor logins for cloud accounts attached to your devices are as vital as firmware patches.
When Updates Stop: Replacement and Risk Management
Every device has a sunset. Once a product reaches EOL or a manufacturer misses its declared support window, assess its role and exposure. High-risk categories—routers, cameras, entry systems—should be replaced promptly. If a connected device guarding your home no longer receives fixes, treat replacement as a safety task, not a luxury purchase. For lower-risk kit, reduce privileges: revoke cloud access, block outbound connections in your router, or isolate it on a guest SSID.
Plan the swap. Back up settings where possible, migrate accounts, and factory reset the old unit to erase personal data. Many retailers and councils offer e‑waste recycling; return devices responsibly. If community firmware exists (for example, open-source router software), weigh benefits against the learning curve and any warranty implications. The priority is maintained patching, not tinkering for its own sake.
Finally, vote with your wallet. Prefer vendors with documented security lifecycles and proven delivery against them. In the UK context, the PSTI framework means manufacturers must state a support duration; keep a record of that promise. When a brand fails to deliver, switch. Consistent consumer demand for long-term updates reshapes market incentives faster than any regulation alone.
The UK Landscape: Standards, Warranties, and What to Expect
The UK’s Product Security and Telecommunications Infrastructure requirements set a baseline: unique or non-guessable default credentials, a public vulnerability disclosure policy, and a declared minimum period for security updates. While the rules stop short of mandating a specific monthly cadence, they push transparency, letting you compare devices on support longevity. The guidance aligns with ETSI EN 303 645 principles, which many reputable brands already follow.
What does that mean in practice? Expect clearer packaging and product pages stating “security updates provided until [date].” Major smartphone makers now advertise longer horizons—some promise up to seven years of security updates—while ISP-supplied routers increasingly auto-update in the background. Scrutinise the small print: is the commitment security-only or full OS features, and does it cover all models sold in the UK? Keep receipts and screenshots of support promises; they help when negotiating repairs or replacements during the advertised window.
For households, the outcome is simple: better information at the point of sale. Use it. Choose devices with the longest stated support that still fit your budget, and annotate your calendar with those end dates. That small administrative habit turns a vague risk into a manageable timetable.
Security updates are not a nuisance; they are maintenance for the digital fixtures of modern life. Build a routine, prefer brands that publish timelines, and treat unsupported devices as temporary guests on your network, not permanent residents. The cost of diligence is small compared with the fallout from a compromised router or camera. Make updates boring, predictable, and automatic—then get on with your day. How will you map your home’s devices, set your preferred cadences, and decide which upgrades earn a place on next year’s budget?
