One morning, you wake up to find your business website showing a strange message – “This site may be compromised.” Your contact forms are gone, pages are redirecting, and customers can’t place orders. It’s every business owner’s nightmare, and yet, it happens far more often than you think. According to recent reports, WordPress powers around 43% of all websites, making it a top target for hackers.
That’s why security isn’t just a technical concern. It should be your business priority. When you hire WordPress developers, you’re not merely paying them to design or build your site but also to protect your digital storefront. You should expect your developers to write secure code, vet every plugin they install, manage updates proactively, back up your data, and monitor WordPress vulnerabilities continuously.
This blog highlights the key WordPress security responsibilities your developers should handle – from securing code and plugins to managing updates, backups, and vulnerabilities.
Understanding WordPress Security
WordPress itself is built with strong security foundations. The real risks usually appear when a website isn’t maintained properly or when shortcuts are taken during development.
Every WordPress site has a few key layers – the core software, themes, plugins, hosting environment, and user access. If any of these layers are weak, your website becomes an easy target. Outdated plugins, poorly coded themes, or unused admin accounts are some of the most common entry points for attackers.
Your developers should treat security as an ongoing responsibility, not a one-time setup. That means choosing only verified plugins and keeping them updated, using strong authentication, and applying patches as soon as they’re released. They should also test updates in a staging environment before going live to avoid downtime or conflicts.
Most importantly, good developers think ahead. They plan for worst-case scenarios by setting up regular backups, monitoring activity logs, and enforcing WordPress security techniques and best practices from day one.
Essential WordPress Security Responsibilities for Developers
Your WordPress website holds customer data, transactions, and reputation. If security isn’t handled correctly, all of them can vanish overnight. Below are the key areas your developers should actively manage to keep your site protected, stable, and compliant:
1. Secure Coding in WordPress: Sanitization, Validation, and OWASP Standards
Every strong WordPress site starts with disciplined coding. Your developers should write code that’s clean, well-documented, and follows WordPress coding standards. They must sanitize every user input and validate every form submission to prevent injection attacks.
Ask your team if they follow OWASP guidelines – a globally recognized list of the most critical web application security risks, including injection flaws, broken authentication, and sensitive data exposure. A professional developer never copies code from random sources or installs “nulled” plugins and themes. Those shortcuts often contain hidden malware or backdoors that compromise your entire server.
Secure coding also includes escaping output. This ensures that any user-submitted content (like comments or form fields) can’t execute malicious scripts.
2. Managing WordPress Updates: Core, Plugins, and Themes
Outdated WordPress core files or plugins are the number one reason websites get hacked.
You should expect your developers to manage a clear update routine. That implies reviewing release notes, testing updates in a staging environment, and only pushing them live after ensuring everything works as intended.
A good developer doesn’t rely on “auto-update and hope.” Instead, they have a scheduled maintenance plan monthly or quarterly.
3. User Access Control: Roles, 2FA, and Password Policies
Developers should set up role-based access control. This ensures that each user gets only the permissions they need.
For example, your content team might need to publish posts, but they don’t need admin rights. Your developers should understand this difference and enforce it.
They must also encourage two-factor authentication (2FA) for admin users and require strong, unique passwords. Too many breaches happen simply because someone reused an old password or shared credentials over email.
Your developers should create a clear user management policy and review accounts regularly to remove inactive users. When an employee or contractor leaves, access must be revoked immediately.
4. HTTPS and SSL: Encrypting Your WordPress Website
A secure website should always run on HTTPS. If you still see a “Not Secure” message in your browser, your developers are missing a critical step.
In that instance, they must install and configure SSL/TLS certificates properly so all data exchanged between your site and visitors remains encrypted.
For e-commerce or membership websites, encryption doesn’t stop at HTTPS. Developers should ensure sensitive data is encrypted both in transit (via HTTPS) and at rest, using secure database practices and server-level encryption where applicable.
Search engines also reward HTTPS sites with higher rankings. So, this one step boosts both your security and SEO.
5. Use Trusted WordPress Security Plugins and Firewalls
Plugins extend functionality but also introduce risks. A professional developer should evaluate each plugin carefully before installing it. They’ll check for factors like update frequency, active installs, developer reputation, and compatibility with your WordPress version.
Your developers must also limit how many plugins are used. More plugins mean more potential weak points. Every plugin should serve a clear business purpose.
Beyond plugins, they need to set up a Web Application Firewall (WAF) using tools like Wordfence, Sucuri, or Cloudflare. These systems filter out malicious traffic, block brute-force attacks, and flag unusual activity before it becomes a problem.
6. Automated WordPress Backups and Disaster Recovery Plans
A security plan isn’t complete without reliable backups.
Your developers should set up automated, off-site backups – daily for busy sites or at least weekly for others. These backups must include both your database and media files. It’s equally important that your developers test restoration occasionally. A backup that can’t be restored is no backup at all.
They also have to maintain version control through Git or similar tools. This allows them to roll back to stable code if something breaks. During instances of accidental deletions or plugin failures, this saves significant time and money.
7. Real-Time Monitoring and Malware Scanning for WordPress
Security is not “set it and forget it.” Your developers should install continuous monitoring tools that watch for file changes, malware, and suspicious logins. Tools like Wordfence, iThemes Security, or MalCare offer malware scanning, login protection, and real-time alerts. Some also include firewall capabilities and vulnerability patching.
It’s also important for developers to know how to act when something goes wrong. They need to maintain a simple incident response WordPress security checklist – identifying, isolating, cleaning, and restoring.
Conducting regular audits at least twice a year is another sign of a secure WordPress development approach. These reviews uncover weak spots, outdated plugins, or unnecessary permissions before hackers find them.
8. WordPress Compliance: GDPR, CCPA, and Data Privacy
If you collect customer data, your developers have a responsibility to help you stay compliant with privacy laws like GDPR or CCPA. They have to configure cookie consent banners, data retention policies, and secure contact forms that prevent spam and leaks.

Key Questions to Evaluate Your WordPress Developer’s Security Approach
When it comes to your website’s security, asking the right questions helps you understand how seriously your developers take protection. Here are key questions to guide your discussion:
- How do you manage WordPress updates and plugin vetting? By asking this question, you can know whether they regularly test and apply updates without risking your live site.
- Do you use a staging environment before making changes live? It’s another very important question to ask. It shows whether they test features and patches safely before deployment.
- How often do you perform security audits or vulnerability scans? Regular scanning keeps your website protected from unnoticed threats.
- What’s your plan if the site ever gets hacked? If the developer answers this question correctly, you can be assured that they follow a defined recovery process – backups, malware removal, and review steps.
- How do you handle user data and compliance? WordPress developers should mention encryption, GDPR alignment, and access control.
Final Thoughts: Make WordPress Security a Business Priority
WordPress security is a continuous partnership between you and your developers. When your team follows the above techniques, the benefits go beyond WordPress website protection. This way, you can also safeguard your business reputation and trust. So, stay involved. Ask questions, review your developer’s security process, and make sure protection is part of every update, not an afterthought.
