How to Protect Your WordPress Website on Public and Untrusted Networks
As working remotely, freelancing, and being generally mobile has become the norm, it is no wonder that people often manage their WordPress sites from locations with little or even no control over the Wi-Fi being used – coffee shops, airports, and hotels have their own Wi-Fi and you cannot really be aware or in control of how they are secured, to name a few. While all of these factors make remote WordPress management convenient, they may be the perfect setup for a cyberattack to succeed.
Having a secure WordPress installation goes well beyond just having a strong password or having a top-notch hosting provider. From the physical device you access the site from, your connection and even what is running on your site all play a role in what makes your web property secure. In case one of these aspects is overlooked and there is no monitoring, then it is just a matter of time before attackers can infiltrate an account or access a site without being authorized.
Familiarizing oneself with the impact public networks have on a WordPress website and the protection methods a website owner can use can help reduce risks to your site and account, which might have happened unintentionally. By taking advantage of measures such as encrypted connections, keeping WordPress and all other software to the latest version and being very careful of your WordPress site privileges, multiple layers of protection will be added which will make remote WordPress administration reasonably safe.
Why Public Wi-Fi Can Be Dangerous for WordPress Administrators
While public Wi-Fi networks are convenient, they are typically not very securely set-up or even managed, meaning that users have very little control over the security aspect. Poor setups, hacked networks or even fake hotspots are just a few examples that might lead to an administrator account being taken over by an attacker.
To some extent every activity performed on a WordPress website through a public Wi-Fi network, such as changing settings, uploading content, managing user groups or accessing the dashboard, can be unsafe if that network is in the hands of an attacker as well. Even though each and every public network is not a risk to security, the fact is that there is simply no insight into it and so a website owner has to be very careful with all kinds of security steps on device, account and application levels as well as at the network level.
In fact, you can get a deeper insight through reading this article of ours that discusses how secure networks make a big difference in the speed and reliability of a WordPress website.
Always Use HTTPS When Accessing WordPress
HTTPS is one of the very important security features of websites. It should definitely be turned on across a WordPress installation to protect the data. It prevents the content that a user is transferring back and forth from the browser and the website from being understood by someone outside the connection.
This is especially important for WordPress administrators when a login involves session information and an account to access the dashboard. It is vital that a website owner is aware that the website uses a valid SSL/TLS certificate, and that all the content, both for visitors and administrators, is always on the secure HTTPS pages.
The only reason why using HTTPS may not be an entirely risk-free solution is that while it can guarantee the secrecy of communication with the site, it does not automatically prevent attackers from gaining control of the user’s device and intercepting other user’s traffic over the same network.
Because of that, the best approach is to combine HTTPS with other security measures particularly at the time when the user is accessing the site via unfamiliar or public networks.
Use a VPN When Managing WordPress From Untrusted Networks
A Virtual Private Network can provide another layer of protection when accessing WordPress through a public or unfamiliar connection. A VPN encrypts traffic between the user’s device and the VPN server, making it more difficult for other people on the local network to inspect that traffic.
This can be particularly useful for freelancers, agencies, developers, and business owners who regularly manage websites while traveling or working remotely. Instead of relying entirely on the security of the public network, a VPN creates an additional protected connection for internet activity.
However, not every VPN service provides the same combination of privacy, security, performance, and features. Users should research providers carefully before choosing one for regular work.
For people choosing between Surfshark or NordVPN, comparing the two services can help identify which option better fits their privacy, security, performance, and connectivity requirements. A detailed comparison can be found in this Cybernews comparison of NordVPN and Surfshark.
A VPN should not replace WordPress security practices. Instead, it should be considered another layer within a broader security strategy.
Protect the WordPress Login With Strong Authentication
The user login is one of the most vulnerable parts of any WordPress website. If a cyber-criminal were able to get hold of the administrator account, they could do virtually anything to the site such as change its content, edit plugins/themes, alter or delete users and change configurations.
We advise administrators to always use strong and unique passwords for WordPress sites that are not similar to those used on other services or social networking sites. If you reuse passwords and one of them gets stolen at another service, it might compromise the security of your WordPress site.
Multi-factor authentication adds another line of the defense. A password is not the only form of verification, and the user is asked to provide an extra one, e.g. a security token, a biometric scan, etc., which would make access without the password a hard task even if the user’s WordPress password gets into the wrong hands.
Website admins should also realize not every person who just happens to walk in will gain access because there is this thing called WordPress roles. With WordPress user roles, a company’s website can grant people only the level of privileges that they need to carry out their duties.
Avoid Managing Sensitive Settings on Unknown Devices
Not only public networks but also physical devices you access WordPress through represent a potential source of cyber-attacks.
Malicious apps, spyware, keyloggers, cookies (and others) on borrowed computers from hotels, libraries or co-working centers could be the reason you were unable to detect these security threats at your machine while logging in. It is possible to reveal the login credentials or administrative sessions while entering the WordPress dashboard from such a machine.
Website owners should use their trusted, private desktops and smart-phones for WordPress admin only when they must. It goes without saying that they must be the latest versions of the OS, browser, anti-malware programs, screen lock protection, and similar stuff.
In exceptional cases when a shared computer really must be used, for instance in an emergency, administrators should avoid automatic password-saving and ensure logging out fully is done after the session and also limit performing highly sensitive tasks.
Keep WordPress Core, Plugins and Themes Updated
A secure network cannot compensate for vulnerable software. WordPress websites rely on several components, including the WordPress core, plugins, themes, PHP, and web server, so keeping them updated is an important part of website security.
Developers regularly release updates to fix bugs, compatibility issues, performance problems, and security vulnerabilities. Running outdated software can leave known weaknesses that attackers may exploit. Website owners should maintain a regular update routine and remove plugins or themes that are no longer needed, as unused software can increase the website’s attack surface.
Regular software maintenance can also improve website reliability. For more information, WordPress administrators can read why regular software updates are essential for website performance and security.
Updates should be tested when possible before being applied to important production websites, especially when a site relies on multiple plugins or custom functionality.
Be Cautious What You Do on Public Networks
The level of risk that each WordPress task presents differs from one another. Checking the numbers or looking at content probably won’t have the same bad consequences as changing payment options, altering security settings or installing plugins.
Unless the network connection is trusted to be secure, remote login or other sensitive activities should be delayed and performed via another network at a different time if possible. If the task is urgent, the safest solution would include the combination of using HTTPS, the WordPress admin on a device that cannot be accessed by other people, having a password that is different every time and, possibly, connecting to a public network via an encrypted channel (e.g. a VPN).
Actually, the goal is not at all to deny access to a remote WordPress website. What the administrator needs to know, however, is the fact that doing any sensitive actions from an environment which is not controlled can lead to serious consequences.
Remote teams who regularly travel will benefit from knowing this.
Secure All Your WordPress-User Devices
WordPress security should never be seen just in terms of your website. Any computer, tablet or smart phone that can be used to log into a WordPress admin dashboard should be considered as a critical part of your web property’s security perimeter.
Closing off the loopholes like leaving outdated OS, browsers and software is just one of many ways to make life harder for criminals. Users shouldn’t even consider downloading unknown files or visiting the dark and shady corners of the web without a good reason. Email should be your main means of communication; if not, your inbox won’t be full of malicious attachments. Phishing is just another major problem because a cybercriminal could impersonate a service provider of your host, WordPress, a plugin developer or a security company with the aim of getting you to give away your login details.
Administrators must refrain from clicking on links in suspicious security alert messages. They should contact the service independently before taking any action with regards to those alerts.
Limit User Permissions in WordPress
Having administrator access to all the website users does not make the website any more secure. On the contrary, if any user gets an admin’s credentials it could allow the hacker more opportunity to harm the website.
Through the WordPress user roles functionality site owners can allow people only the minimum level of access and control for their duties. In other words, someone working mainly to publish or edit articles does not need to be able to install new plugins or to modify the WordPress kernel.
Applying a principle where only necessary privileges are given at minimum can significantly restrict the extent to which a hacked user can get to different parts of the site or change things in there. Besides that, website owners should regularly check user accounts and remove access for former employees, contractors, freelancers, and any other user accounts that are not being used.
Configuring Caching Without Exposing Private Information
In WordPress performance, caching is a major component. However, when a website is storing a lot of user private or personalized information then the configuration of caching must be done very carefully.
Caching is great for public pages in such a way that it enables the delivery of static content to various users at the same time. For pages that display highly personalized data, however, they may have to look into other types of strategies for caching. Care should be taken to avoid having private content being cached in the web server, such as login forms, shopping cart pages, personal dashboards, order pages, etc.
The wrong caching setup which fails to acknowledge the differences between the public vs. private content might end up displaying information to the wrong visitors. Hence, performance optimizations should, in any case, be weighed against security & privacy issues.

Remote Teams Require Clear Security Guidelines
Having to remotely administrate a WordPress website that is accessed from many different locations and devices can become a problem when it comes to security. While developers might prefer working in a home office, the content creation team may opt to use co-working facilities and a marketing squad might do their job while moving about. The only thing that matters is having consistent enforcement of security rules.
A set of clearly stated guidelines must include everything related to what equipment is acceptable to be used (e.g. your own laptop or the company’s notebook), password policies, MFA requirement, using a secure channel with the help of a VPN, keeping all software versions up-to-date, controlling and limiting users’ privileges, etc. It is equally important that employees know what types of information they should never put into third-party apps, and if sharing sensitive data over open internet channels, even a small mistake can lead to serious consequences.
Uniformity of security standards reduces risks coming from human errors and makes remote access safer. In addition, if a group of employees is working from locations using public networks, it is very essential that they are being shown safe practices for WordPress remote access in order to prevent administrators’ credentials of being stolen.
Keep a Surveillance on Any WordPress Activity That Seems Odd
Safeguards are very important but website owners should also be watching for suspicious activity.
You know the things, strange admin users added at random, some unknown plugins, several failed login attempts, the modification of site pages, redirects that do not make any sense or the content suddenly changes. All of these are possible indicators and a change in the way one manages the site might make it possible to spot a problem before it is too late and everything goes wrong due the breach.
Website backups are also a big part of the plan as with good backups if a site gets hacked, there’s a way for a website to be restored. In addition, if you backup your website to the same place your site is, the attacker who is able to get through and access all your data and backups might also have a hard time to find out what is what.
WordPress Security and Performance Should Not Be Thought of as Separate
Website security and performance are often discussed separately, but they are closely connected. Outdated plugins can create security vulnerabilities while also causing compatibility or performance issues. Poorly configured caching can affect loading speeds while potentially creating privacy problems.
A well-maintained WordPress website should therefore balance performance optimization with security controls. Efficient caching, updated software, secure authentication, reliable hosting, and proper access management can all contribute to a healthier website environment.
Website owners should avoid treating speed optimization as something that happens independently from security. Changes to caching, plugins, themes, and server configurations can affect both areas and should be evaluated accordingly.
Develop a Secure Remote Management Process for WordPress
Protecting a WordPress website on public and untrusted networks does not require eliminating remote work. Instead, it requires consistent security practices around remote access.
Administrators should use HTTPS, strong passwords, multi-factor authentication, updated software, trusted devices, and appropriate user permissions. A reputable VPN can also provide an extra layer of protection when using unfamiliar networks. Website owners should maintain reliable backups, monitor activity, remove unnecessary software, and ensure caching rules do not expose private information.
Since public Wi-Fi remains common for remote workers and website owners, WordPress security should cover the entire environment, including the website, hosting, accounts, devices, applications, and network connections. Securing each layer can significantly reduce risks while allowing websites to be managed remotely.
