The Security Case for Finally Upgrading Your Magento 1 Store

If your ecommerce store is still running on Magento 1, you're not just running old software: you're running unprotected software. Adobe officially ended support for Magento 1 back in June 2020, which means there have been no official security patches for well over five years. Every new vulnerability discovered since then has stayed open, and attackers know it.

We still speak to store owners who are reluctant to move because their Magento 1 site "still works fine." The trouble is that security risk doesn't show up as a broken page: it shows up as stolen card data, a blacklisted domain, or a call from your payment provider asking why you're no longer PCI compliant. Here's what's really at stake, and how Nublue can help you move on from Magento 1 without the upgrade turning into its own emergency.

Store security: the risk you can't patch away

Magento has long been one of the most targeted ecommerce platforms, and Magecart-style skimming attacks, where malicious code is injected to quietly capture customer card details at checkout, remain a persistent threat across outdated Magento installs. Because Magento 1 no longer receives security updates, any vulnerability found in the platform today is a vulnerability that will never be fixed at the source. Store owners are left relying entirely on third-party protection to hold the line.

This isn't a theoretical risk. Waves of mass Magecart campaigns have specifically targeted outdated Magento sites, and unsupported stores are consistently the easiest targets because known exploits are public and unpatched. On top of the direct threat of card skimming, running an unsupported platform also puts your PCI DSS compliance at risk, and non-compliance can mean fines, liability for fraud losses, and payment providers refusing to process your transactions at all.

Performance gains: a faster store, not just a safer one

Security is the headline reason to move, but it's rarely the only one. Magento 2's architecture was built for speed and scale in ways Magento 1 simply wasn't designed for. Full-page caching with Varnish, improved indexing, a more efficient checkout flow, and better handling of large product catalogues all add up to real gains in page load times. On an ecommerce site, that matters commercially as well as technically: faster pages convert better, rank better in search, and cope far more gracefully with traffic spikes around sales and seasonal peaks.

New features and capabilities you're currently missing out on

Magento 2 (and the modern Adobe Commerce ecosystem it sits within) has moved on a long way from where Magento 1 was left. A streamlined checkout, a modernised admin experience, built-in support for progressive web apps and headless/composable storefronts, better multi-channel and B2B capability, and a far more active extension marketplace are all things Magento 1 merchants simply can't access. Every year you stay on Magento 1, the gap between what your store can do and what your competitors' stores can do grows a little wider.

Compatibility and support: the walls are closing in

It isn't only Adobe that has moved on from Magento 1; the wider ecosystem has too. Payment gateways, extensions, and third-party integrations are steadily dropping Magento 1 support, and newer versions of PHP and other underlying infrastructure are no longer guaranteed to work with it either. That leaves store owners in an increasingly awkward position: staying on infrastructure that's harder to host securely, harder to find developer support for, and harder to keep talking to the rest of your tech stack.

How Nublue can support your upgrade

We know that "just migrate to Magento 2" is easy to say and harder to plan for, especially with a live store, existing integrations, and customers to protect throughout. That's why we don't leave you to figure it out alone.

Protected right now with Sansec Shield

Upgrading a live ecommerce store is rarely an overnight job, and you shouldn't have to leave your store exposed while you plan and execute the move properly. That's where Sansec Shield comes in. We can put it in front of your Magento store immediately, giving you:

• Every known Magento attack vector blocked in real time: virtual patching without waiting for the official fix.
• Zero false positives, so legitimate traffic and store operations are never disrupted.
• Zero performance impact on page load.
• Protection against new CVEs from the moment they're disclosed.
• Time to patch properly, on your schedule, instead of a rushed emergency hotfix at 2am.

In other words, Sansec Shield buys you breathing room. It closes the security gap Magento 1 has left open, so your upgrade to Magento 2 can happen as a properly planned project rather than a reaction to a breach.

This isn't just theory for us. We've been running Sansec Shield across client stores for extended periods, and it's proved its worth: catching vulnerabilities before they turn into incidents, giving us solid evidence that a store is genuinely secured, saving real time on patching and development work, and giving clients the confidence to hold off on an immediate upgrade when their own scheduling doesn't allow for one right now.

Sansec also runs recurring, one-off, and detailed scans across your codebase, so you can keep verifying your store stays secure and up to date over time, rather than treating security as a single point-in-time check.

Upgrades with our partner, CTI Digital

For the development and migration itself, we work hand-in-hand with our partner, CTI Digital, whose ecommerce team has deep, dedicated Magento expertise. Together, we plan and deliver upgrades that protect what already works on your store (your catalogue, your integrations, your customer experience) while rebuilding it on a platform that's actually supported. You get specialist Magento development expertise paired with the hosting and infrastructure knowledge to bring it all together safely.

Don't wait for the breach to force the decision

Every month you stay on Magento 1 is another month of unpatched risk, slower pages, missing features, and shrinking support from the wider ecosystem. The good news is you don't have to tackle it alone, and you don't have to leave your store unprotected while you plan the move.
