Handing your WooCommerce store to a developer or agency is a moment of significant trust. You’re giving someone access to your customer data, your payment flows, your brand — and in most cases, you have no straightforward way to verify whether the person building or maintaining your site actually understands security. Most store owners don’t know the right security questions to ask a WordPress developer before work begins, which means security gaps get built in from day one and only surface when something goes wrong.
This isn’t a developer interview guide for hiring managers. It’s a practical checklist for store owners — people who run a business, not a code repository — who want to understand what competent WordPress security looks like so they can ask informed questions and recognise weak answers. The goal isn’t to catch developers out; it’s to separate those who treat security as standard practice from those who treat it as an optional extra.
The questions here cover the full picture: how developers handle access and credentials, how they approach hardening and updates, what their backup and recovery thinking looks like, and what happens after the project ends. For each area, you’ll find what a thoughtful answer sounds like — and what should give you pause.

Always test in a staging environment first and maintain verified backups before modifying production systems.
Access, Credentials, and Who Controls What
The first category of security questions to ask any WordPress developer is about access — who gets it, in what form, and what happens to it when the project is over. This sounds administrative, but it’s where a significant number of security incidents begin.
A developer who takes security seriously will ask for the minimum access they need to do the job — not admin credentials to everything by default. For a build project, they should be working in a staging environment, not directly on your live store. They should create their own user accounts rather than asking to share yours, and those accounts should be removed or deactivated when the engagement ends.
What to ask
“How will you handle login credentials during the project?” A good answer involves creating a named developer account with appropriate permissions, never sharing passwords over email or chat, and a clear process for revoking access at handover. A weak answer is “just send me your admin login” — that’s a red flag regardless of how trusted the relationship feels.
“What do you do with credentials and access after the project ends?” Every account created for a project should be removed or have its password rotated. If a developer can’t answer this question clearly, you’re likely to find ghost accounts in your WordPress user list six months later — accounts that remain valid entry points.
“Will you be working directly on the live site or on a staging environment?” Staging is standard practice for any meaningful development work. Working directly on a live WooCommerce store during business hours is a risk to uptime and to data. The answer should be staging, with a defined process for deploying to live.
One related question worth asking: “Do you use two-factor authentication on your own accounts?” A developer who doesn’t protect their own credentials is a weak link in your security chain regardless of how well they build.

Hardening: What Gets Locked Down Before Launch
A default WordPress installation ships with a number of known weaknesses. A developer who understands security closes them before handing the site over. One who doesn’t will leave you with a store that looks complete but has predictable entry points any automated scanner can find in minutes.
You don’t need to know the technical details of every hardening step to ask about them intelligently. What you’re listening for is whether hardening is part of their standard delivery or something they do if specifically asked.
What to ask
“What WordPress hardening steps are included in your standard build?” A solid answer mentions things like: disabling file editing from within the WordPress dashboard, restricting access to sensitive areas, removing publicly visible version information, disabling features your store doesn’t use (XML-RPC, directory browsing), and setting appropriate security headers. If the developer needs you to define what “hardening” means, that’s informative.
“Will the uploads folder be configured so it can’t execute scripts?” Your uploads folder stores images and documents — it has no business running programs. Attackers know this is often misconfigured and use it to plant malicious code. The developer should confirm this is handled as standard; the fix takes minutes but is frequently skipped.
“What security headers will be in place at launch?” Security headers instruct browsers how to behave when loading your site — they reduce the risk of clickjacking, content injection, and data leakage. A developer who can’t name any headers they plan to configure hasn’t thought about this layer. After handover, you can run a free check at guardfos.com/scanner to see what’s actually in place — it checks exactly these configuration gaps.
“How will you handle the WordPress login page?” The default login page address is publicly known. Limiting who can access it, or changing its location, reduces automated brute-force attempts. Not every developer does this by default; the answer tells you whether they’ve thought about attack surface.

Updates, Plugins, and Ongoing Maintenance
The majority of WordPress compromises happen through outdated software — specifically outdated plugins and themes. A developer who builds a well-hardened site but leaves updates unmanaged has addressed the construction quality while ignoring the maintenance schedule. For WooCommerce stores, this is a recurring liability.
This category of questions matters most if you’re engaging a developer or agency for ongoing maintenance rather than a one-time build. But even for build-only projects, it’s worth understanding what they’re handing you and whether it’s set up for maintainability.
What to ask
“How many plugins are you planning to use, and how do you choose them?” More plugins means a larger attack surface. A developer who defaults to installing a plugin for every minor function without evaluating plugin quality, update history, or active install base is building in future risk. A good answer reflects deliberate selection — choosing maintained plugins from reputable developers, avoiding abandoned ones, and questioning whether a plugin is genuinely needed.
“Who handles updates after launch, and on what schedule?” This is one of the most important questions you can ask. If the answer is “that’s your responsibility” and you don’t have a developer on retainer or a managed WordPress security arrangement, you have an unmanaged liability from day one. Updates need to happen consistently — not whenever you remember, not once a quarter.
“What’s your process for testing updates before applying them to the live site?” Applying updates without testing can break functionality — but skipping updates to avoid breakage leaves known vulnerabilities open. A developer with a real process has a staging environment and tests before deploying. “I just update and see what happens” on a live store is the wrong answer.
“How do you handle a plugin that stops being maintained?” Abandoned plugins are a known vulnerability vector. A developer who monitors the ecosystem and has a plan for replacing deprecated software is thinking long-term about your store’s security posture.

Backups, Recovery, and What Happens When Things Go Wrong
No security conversation is complete without asking about backups — and what happens if you actually need to use one. Many store owners assume their host is handling backups adequately. Many are wrong about that assumption, and some discover it at the worst possible moment.
A developer or agency handing over a WooCommerce store should have a clear, honest answer to backup questions. If they deflect to “your host handles that,” follow up to find out whether that’s actually true and what it covers.
What to ask
“What backup solution is in place, and where are backups stored?” The critical detail is off-site storage. A backup stored only on the same server as your site is not a real backup — if the server is compromised or goes down, both the site and the backup are gone. Backups should be on a separate, independent infrastructure. guardfos, for example, stores backups on Amazon S3 with 90-day retention — that’s the standard a managed service should meet. If your developer is pointing to host-only backups with 7-day or 14-day retention, you should understand the gap.
“How often are backups taken, and how long are they retained?” Daily backups are the minimum for an active ecommerce store. Retention matters too — if you discover a compromise that happened three weeks ago, a 7-day backup window leaves you with no clean restore point. Ask specifically: what’s the retention period?
“Have you actually tested a restore from backup?” A backup you’ve never tested is hope, not protection. A credible developer or managed service can describe the restore process and confirm it’s been validated. “I assume it works” is not an acceptable answer for a store processing customer payments.
“What’s the recovery plan if the site is compromised?” This question separates developers who’ve thought about incident response from those who haven’t. A good answer involves a defined sequence: take the site offline to prevent further damage, identify the compromise, restore from a clean backup, harden the entry point, verify clean. A vague answer — “we’d fix it” — tells you incident response isn’t something they’ve planned for. For context on what recovery actually involves, the guide on recovering a hacked WooCommerce store covers realistic timelines and what slows the process down.

What Happens After Handover — and the Ongoing Security Picture
The most overlooked category of questions covers what happens once the project ends and the developer or agency steps back. For a WooCommerce store, “after launch” is when the real risk accumulates — because the site is live, processing real transactions, and in many cases, the security thinking stops the moment the invoice is paid.
What to ask
“What ongoing security monitoring is in place after launch?” Monitoring means something is watching for suspicious activity — login attempts, file changes, unexpected traffic spikes — and alerting someone who can act on it. If the answer is “you’d need to set something up” or “WordPress sends you an email if there’s a problem,” monitoring isn’t in place. Ask specifically what triggers an alert and who receives it.
“Who owns the domain, hosting account, and any third-party service accounts?” This isn’t directly a security question, but it becomes one the moment a relationship ends badly or an agency closes. Your domain, DNS settings, hosting credentials, and email service accounts should be in your name and under your control. Developers who register domains or set up hosting under their own accounts create a dependency that can turn into a serious problem. Ask for written confirmation of who owns what.
“What’s your process for notifying me about security vulnerabilities that affect my site?” Critical vulnerabilities in WordPress core, WooCommerce, and popular plugins get disclosed regularly. A developer or agency on retainer should have a process for monitoring these and alerting you — or acting on them directly. If there’s no defined process, that’s a gap. The guardfos article on critical vulnerability email warnings covers what those alerts typically look like and what to do when they arrive.
“Do you offer any form of security guarantee or SLA?” Most developers don’t, and that’s honest — a single developer can’t guarantee a site won’t be compromised. But the question surfaces whether they’ve thought about accountability. A managed security service offers defined response times and ongoing accountability; a one-off build project typically doesn’t. Understanding the difference helps you decide whether to supplement the developer relationship with a dedicated security layer.
The honest reality is that most WooCommerce store owners aren’t in a position to evaluate developer security practices in depth — that’s precisely the gap that lets avoidable vulnerabilities through. A developer who welcomes these questions and answers them clearly is worth significantly more than one who deflects or treats them as unnecessary. Security isn’t a build phase checkbox; it’s an ongoing operating condition for any store that processes customer payments.

Frequently Asked Questions
What are the security issues with WordPress?
The most common WordPress security issues are outdated plugins and themes with known vulnerabilities, weak or reused admin passwords, misconfigured file permissions, absence of security headers, publicly exposed version information, and no active monitoring. WooCommerce stores face additional risks because they handle payment data — making them higher-value targets. Most compromises exploit one of these gaps, and most are preventable with consistent maintenance and proper hardening. No system is completely immune, but closing these known weaknesses removes the vast majority of automated attack opportunities.
What questions should I ask a developer?
Beyond timeline and cost, ask your developer: how they handle credentials and access during and after the project; what hardening steps are included in their standard delivery; who handles updates and on what schedule; where backups are stored and how often restores are tested; and what monitoring is in place after launch. These questions reveal whether security is part of their standard practice or an afterthought. A developer who answers them clearly and specifically is demonstrating competence. One who deflects, generalises, or treats them as unnecessary is signalling a gap.
What should a WordPress developer know about security?
A competent WordPress developer should understand the standard hardening checklist: disabling unnecessary features like XML-RPC and directory browsing, implementing security headers, restricting the uploads folder from executing scripts, managing user permissions carefully, and keeping all software current. They should also understand staging environments, backup strategies, and basic incident response. For WooCommerce, PCI DSS considerations and payment security basics matter too. This isn’t specialist knowledge — it’s table stakes for anyone building or maintaining a store that processes customer data.
How do I know if my developer handles security properly?
Ask specific questions and listen for specific answers. Vague responses like “we follow best practices” or “WordPress has built-in security” are warning signs. Strong answers name concrete steps: hardening measures applied at launch, a defined update schedule, off-site backup storage with tested restores, and a process for notifying you about new vulnerabilities. After handover, you can run a free check at guardfos.com/scanner to see what security configuration gaps actually exist in the finished site — missing headers, exposed version info, XML-RPC status, and more.
Who is responsible for WordPress security — me or my developer?
It depends on what’s been agreed in writing — and often nothing has been. A build-only developer is typically responsible for delivering a secure site at handover; ongoing security then falls to you unless you have a maintenance retainer or managed security service in place. Many store owners discover this gap only after an incident. The practical answer: clarify scope in writing before the project starts, confirm who handles updates and monitoring after launch, and consider a managed WordPress security service to cover the ongoing layer that most developer relationships don’t include.
What security questions to ask a WordPress developer about backups?
Ask where backups are stored — specifically whether they’re off-site, not just on the same server or hosting account. Ask how frequently backups are taken (daily is the minimum for an active store), how long they’re retained, and whether a restore has actually been tested. A backup stored only on the same host as your site offers limited protection if that host is compromised. Retention matters too: if you discover an infection that happened three weeks ago, a seven-day backup window leaves you with no clean restore point.
Conclusion
The point is this: security questions to ask your WordPress developer aren’t about catching people out or demanding technical certifications. They’re about distinguishing professionals who build security in from those who bolt it on — or skip it entirely. A developer who welcomes these questions and answers them with specifics is exactly the kind of person you want working on a store that processes real customer payments. One who deflects or treats them as excessive is telling you something important before any money changes hands. Ask the questions early, get the answers in writing where it matters, and supplement whatever your developer delivers with ongoing monitoring and maintenance — because a well-built launch is only the beginning.
