For small businesses, this poses a serious challenge. Limited budgets and lean teams can leave websites exposed to vulnerabilities—especially without a solid security plan in place.

Website security isn’t just a one-time fix—it’s a continuous process of protecting your site and data from threats like malware, data breaches, and hacks. As technology advances, so do the methods of attack.

The good news? Prevention is powerful. With the right tools and support, like those from Network Solutions, you can stay ahead of threats and keep your digital presence secure. Read on to learn how.

What is website security?

At its core, web security is all about safeguarding sensitive information—whether it’s customer passwords, personal details, or financial data. By encrypting this information and using secure connections (like HTTPS), you ensure that even if someone tries to intercept the data, it stays protected.

A secure website builds trust by keeping all data exchanged between your site and users encrypted and shielded from unauthorized access.

But security isn’t something you set and forget. It’s an ongoing process. Regular vulnerability scans, timely software updates, and real-time monitoring tools are crucial for detecting and addressing threats before they become serious problems. Staying proactive keeps your website one step ahead as cyber threats continue to evolve.

Why businesses need to invest in website security

Web security doesn’t just protect your site—it directly influences your business’s success.  Here’s why it’s essential to invest in website security:

Protects your sales and revenue

A single cyberattack can take your website offline, especially during high-traffic periods like sales events or peak shopping seasons. Downtime means missed opportunities, frustrated customers, and lost revenue. With strong web security, you reduce the risk of disruptions and keep your digital doors open 24/7.

Boosts your SEO and search visibility

Search engines favor secure websites. Website with HTTPS through an SSL certificate are not only ranked higher but are also more likely to appear in search results. On the other hand, if your site isn’t secure, search engines may penalize you, pushing you down in rankings.

Investing in website security helps ensure your site isn’t flagged as “unsafe” by search engines. It boosts your SEO, increases organic traffic, and helps you stand out from competitors. A secure site means better visibility in search results, which means more potential customers will discover your business.

Strengthens your brand reputation

Trust is everything online. A secure website signals to visitors that their data is safe, making them more likely to complete purchases or share information. On the flip side, a data breach or visible security warning can seriously harm your brand’s image. Investing in web security shows customers you take their safety seriously, and that builds lasting loyalty.

5 most common website security threats

Here are some of the common dangers lurking online that website security helps to defend against:

Malware

Malware refers to any malicious software designed to damage, disrupt, or exploit websites and their users. It’s a relentless threat—over 450,000 new variants are detected globally every single day.

Some of the most common types include:

• Viruses.  Attach to clean files and spread throughout your system.
• Worms. Self-replicate and spread across networks without needing a host file.
• Ransomware. Locks your data and demands payment for its release.

Malware can be used to steal sensitive information, hijack your site to spread spam, or gain backdoor access for future attacks. Often, it sneaks in through outdated plugins, themes, or software vulnerabilities.

Phishing attacks

Phishing is a deceptive tactic where attackers pose as legitimate entities to trick users into revealing sensitive information, like passwords, credit card numbers, or login credentials. Shockingly, phishing is behind 41% of data breaches on the web.

These scams often appear as convincing emails or fake websites that mimic real brands or services. While phishing primarily targets your users, it can also severely damage your website’s credibility if attackers exploit your brand to deceive others. When customers associate your site with security risks, trust—and traffic—can quickly decline.

DDoS attacks

A Distributed Denial-of-Service (DDoS) attack overwhelms your website with massive amounts of fake traffic, causing it to slow down or crash entirely. In 2024 alone, there were over 14.5 million DDoS attacks reported globally, making it one of the most widespread forms of cyber disruption.

While DDoS attacks don’t typically steal data, they can severely impact your business by taking your site offline. This kind of downtime frustrates users, interrupts service, and can lead to lost sales, missed opportunities, and long-term damage to your brand’s reputation.

Staying protected means having the right infrastructure and monitoring tools in place to detect and respond to these threats before they impact your users.

SQL injection

Exploiting vulnerabilities in your website’s database to steal or manipulate data. SQL injection is a common hacking technique where attackers insert malicious code into your website’s database through vulnerable input fields—like login forms, search bars, or contact forms. If successful, these attacks can give hackers the power to access, modify, delete sensitive data, or even take full control of your site.

To defend against SQL injection, it’s essential to validate and sanitize all user inputs, use parameterized queries, and maintain strong database security protocols. Prevention starts with writing secure code and staying on top of system updates.

Brute-force login attempts

Repeatedly trying different usernames and passwords to gain unauthorized access. Brute force attacks involve hackers trying countless combinations of usernames and passwords to gain access to your website. This is an old attack method, but it’s still effective and popular with hackers according to a Kaspersky report.

Websites with weak, reused, or easily guessed passwords are prime targets. Once access is gained, attackers can steal data, deface your site, or install malicious software.

To defend against brute force attacks, use strong, unique passwords, limit login attempts, and enable two-factor authentication (2FA). These simple steps can significantly reduce your risk and help keep unauthorized users out.

Zero-Day Vulnerabilities

Zero-day vulnerabilities are security flaws in software that are unknown to the developer—and have no immediate fix. In recent years, zero-day incidents surged by 50%, with many tied to sophisticated spyware attacks.

What makes them so dangerous is that attackers exploit these weaknesses before a patch becomes available, leaving systems defenseless. Because there’s no early warning, zero-day attacks can cause serious damage before they’re even detected.

To minimize the risk, it’s critical to stay vigilant: apply updates and security patches the moment they’re released, monitor for unusual activity, and use advanced threat detection tools when possible.

How to secure your website in 7 simple steps

Protecting your website from cyber threats is essential to keeping your data safe and your business running smoothly. The good news? There are proven strategies you can use to defend your site against attacks:

Use SSL to encrypt data

One of the foundational steps in website security is protecting the connection between your site and its visitors. An SSL (Secure Sockets Layer) certificate encrypts all data exchanged, making it unreadable to anyone who tries to intercept it.

Once installed, your site automatically upgrades from HTTP to HTTPS, signaling to users (and search engines) that it’s secure. This not only protects sensitive information like login details and payment data but also builds trust and credibility with your audience.

Keep software and plugins up to date

Outdated software is a common entry point for hackers. Cybercriminals often exploit known vulnerabilities in older versions of content management systems (CMS), plugins, themes, and other website tools.

To stay secure, regularly update everything running on your site. Developers release patches and security fixes frequently—ignoring them leaves your site exposed. Wherever possible, enable automatic updates to make sure you’re protected without needing to track every new release manually.

Staying current is one of the simplest but most effective ways to close security gaps.

Monitor your website for suspicious activity

Ongoing monitoring is essential for catching threats before they cause serious damage. Use real-time monitoring tools to detect red flags like repeated failed login attempts, sudden traffic spikes, or unauthorized changes to files.

Many security plugins include automatic alerts and activity logs, so you’re notified the moment something suspicious happens.

For stronger protection, implement a Web Application Firewall (WAF). A WAF filters and inspects incoming traffic to block common threats like SQL injections, cross-site scripting (XSS), and even DDoS attacks, helping your site stay secure and responsive during high-traffic events.

SiteLock by Network Solutions offers cloud-based scanning and real-time threat detection to give you peace of mind while keeping your website safe 24/7.

Use strong passwords and enable Two-Factor Authentication (2FA)

Weak or reused passwords are one of the easiest ways for attackers to gain access to your site. Make sure all admin and user accounts use strong, unique passwords—a combination of upper- and lowercase letters, numbers, and symbols. Encourage (or enforce) regular password updates, ideally every 90 days.

To further protect your site, enable two-factor authentication (2FA). This adds an extra step to the login process by requiring users to verify their identity through a secondary method, such as a code sent to their phone or an authentication app. It’s one of the simplest and most effective ways to prevent unauthorized access—even if a password gets compromised.

Back up your website regularly

Backups are your safety net. Whether it’s a cyberattack, server crash, or accidental deletion, having a recent backup means you can quickly restore your site and avoid permanent data loss.

Set up automated backups that run daily or weekly, depending on how often your site changes. Store backups in a secure offsite location or cloud-based system to ensure they’re safe from the same threats affecting your site.

Choose a secure and reliable hosting provider

Your hosting provider plays a critical role in your website’s overall security. Look for one that offers built-in security features like firewalls, automatic backups, malware detection, and regular server maintenance. A secure host helps shield your site from server-level threats and reduces your risk of being compromised.

For example, Network Solutions offers security features like SSL certificates and advanced monitoring to help keep your site secure and running smoothly. Choosing a host with these protections can save you from potential problems later on.

Advanced security tips for securing your website

Once you’ve covered the basics of website protection, it’s time to take your security to the next level. These advanced strategies can help safeguard your site against more sophisticated threats and keep your digital assets fully protected:

Implement Content Security Policy (CSP)

A CSP helps prevent cross-site scripting (XSS) attacks by specifying which sources of content are allowed to load on your site. This limits the ability of malicious scripts to run in your users’ browsers.

Set Up HTTPS Strict Transport Security (HSTS)

HSTS ensures that browsers only connect to your site over secure HTTPS connections. It helps prevent protocol downgrade attacks and keeps your visitors’ data encrypted at all times.

Restrict admin access

Limit access to your website’s admin area by IP address and consider using VPN access for admin logins. The fewer entry points, the harder it is for hackers to break in.

Scan and harden your database

Go beyond standard validation and regularly scan your database for irregularities. Use tools or services that can harden your database by removing unused data and tightening permissions.

Monitor for file changes

Install security tools that detect unauthorized file changes. These changes can signal malware injections or tampering and catching them early can prevent further damage.

Conduct regular security audits

Schedule periodic audits of your entire website—from code reviews to plugin evaluations—to catch overlooked vulnerabilities before attackers do.

Disable directory listings

Make sure your server is not listing directory contents publicly. If left open, hackers can browse through files and locate sensitive scripts or data.

Steps to take if your website gets hacked

A hacked website can feel overwhelming, but acting quickly can minimize damage and help you recover faster. Here’s what to do:

1. Stay calm and disconnect. Take your site offline temporarily to prevent further harm and protect your visitors.
2. Contact your hosting provider. Many hosting providers offer support for hacked websites. Reach out to them right away—they may help isolate the issue or even assist in cleanup.
3. Change all passwords. Reset all admin, user, and FTP passwords immediately. Use strong, unique combinations.
4. Scan your site for malware. Use a website security tool or plugin to run a full malware scan. This helps identify infected files and suspicious code.
5. Restore a clean backup. If you have recent, clean backups of your site, restoring from them can get you back online quickly.
6. Remove malicious code. Manually or with the help of a security expert, delete harmful scripts or injected code. Some services also offer automatic malware removal.
7. Update all software. Install the latest versions of your CMS, plugins, and themes. Outdated software often leads to vulnerabilities.
8. Strengthen your security. After cleanup, improve your site’s defenses. Add a firewall, enable two-factor authentication, and review user access.
9. Notify users if needed. If user data was compromised, transparency is key. Let your customers know so they can take precautions too.
