Custom websites are meticulously designed and built to fit every contour and complement every aspect of a company’s brand, similar to how renowned fashion designers measure and hand-stitch exclusive outfits for celebrities’ slow walks down the red carpet.

Celebrities opt for such one-of-a-kind creations so they can stand out, make a statement, generate a few headlines, and perfectly project their style to the masses—in short, the outfit works in support of their own personal brand. Similarly, custom websites capture the unique identity and specific needs of an organization and help set them apart online.

However, exclusivity carries certain responsibilities. Just as a couture gown requires specialized cleaning and storage to maintain its pristine condition, custom websites need ongoing attention and expertise to remain secure and functional. Unlike ready-to-wear fashion lines or off-the-shelf website solutions, such custom digital creations rely on developers to implement and uphold robust security measures.

A full-time, in-house team of experienced full-stack developers, which we certainly have here at Rare Bird, can provide constant attention and expertise that many other full-service agencies—who often outsource web development to yet another company—can’t match. This dedicated focus allows for vigilant oversight of every aspect of a website’s creation and maintenance. Unique code and specific configurations—which can make these websites exceptional—can also introduce vulnerabilities if not managed with the utmost care and skill. The ongoing efforts of developers to improve and secure their work help protect a custom website against possible risks.

Plenty of businesses leaders already know the stakes when it comes to website security. A single breach can result in:

  • Loss of sensitive customer data
  • Damage to your brand’s reputation
  • Financial losses (due to downtime or legal repercussions)
  • Compromised intellectual property
  • Loss of customer trust and business

As cyber threats evolve at an alarming pace—what was secure yesterday could well become vulnerable today—ongoing vigilance by a team of experts becomes increasingly important. Such vigilance encompasses a wide array of strategies and techniques, so the following list is far from exhaustive—at least partly because it’s wise to keep certain security tactics close to the vest. (But also, magicians never reveal all of their methods.)

Key Security Considerations in Custom Web Development

Data Protection

The protection of user data is paramount, especially when handling personal and financial information. This involves multiple layers of security:

  • Encryption: All sensitive data should be encrypted both in transit and at rest. This means implementing HTTPS across the entire site and using strong encryption algorithms for stored data.
  • Secure Data Storage: Utilizing secure database systems and following best practices for data management.
  • Compliance: Adhering to relevant regulations such as GDPR, CCPA, or industry-specific standards for e-commerce sites.

Authentication and Access Control

Robust authentication systems are the first line of defense against unauthorized access:

  • Implement strong password policies, encouraging or requiring complex passwords.
  • Use two-factor (2FA) or multi-factor authentication (MFA) for additional security.
  • Employ secure session management to prevent session hijacking.
  • Implement role-based access control to ensure users only have access to necessary resources.

Regular Updates and Patch Management

Software vulnerabilities are discovered constantly, making regular updates crucial:

  • Keep all custom code up-to-date and free of known vulnerabilities.
  • Regularly update third-party libraries and frameworks used in the project.
  • Implement a patch management process to quickly address newly discovered vulnerabilities.

HTTPS Implementation

Securing data in transit is crucial for protecting user privacy and preventing man-in-the-middle attacks:

  • Use HTTPS across the entire website, not just on login or checkout pages
  • Implement proper SSL/TLS configuration with strong protocols and ciphers.
  • Use HTTP Strict Transport Security (HSTS) to prevent downgrade attacks.

The Process: Security in Custom Web Development

Security should be integrated into every stage of the development process, not treated as an afterthought. Our comprehensive approach includes:

Planning and Requirements Gathering

Security considerations should be built into custom web development projects from the ground up:

  • Conduct thorough risk assessments to identify potential vulnerabilities.
  • Define clear security requirements and objectives for the project.
  • Incorporate security-related user stories into the development backlog.

Secure Design

Experts often rely on security-by-design principles to create architectures that are inherently secure:

  • Implement the principle of least privilege in system design.
  • Design with data minimization in mind, collecting and retaining only necessary information.
  • Plan for secure error handling and logging to prevent information leakage.


Rigorous security testing is performed throughout the development process:

  • Conduct regular automated security scans.
  • Perform manual penetration testing to identify complex vulnerabilities.
  • Carry out user acceptance testing with security scenarios in mind.


Secure deployment practices ensure that the production environment is properly locked down:

  • Use secure configuration management tools to maintain consistent and secure server setups.
  • Implement proper access controls and monitoring for production systems.
  • Employ continuous integration and deployment pipelines with built-in security checks.

Maintenance and Monitoring

A commitment to security should extend well beyond the initial launch:

  • Provide ongoing security updates and patches.
  • Implement robust logging and monitoring systems to detect potential security incidents.
  • Conduct regular security audits and vulnerability assessments.

The Importance of Ongoing Vigilance

We work closely with clients to ensure their websites remain secure through:

  • Regular Security Audits: Conducting comprehensive reviews of the website’s security posture to identify and address potential vulnerabilities.
  • Prompt Implementation of Security Patches: Staying on top of security updates for all components of the website, including the core application, plugins, and third-party libraries.
  • Ongoing Learning/Training: Providing ongoing education for both our team and our clients’ staff, as needed, regarding security best practices and emerging threats.
  • Incident Response Planning: Developing and regularly updating plans for responding to potential security incidents, ensuring quick and effective action if a breach occurs.
  • Continuous Improvement: Regularly reassessing and enhancing our security practices based on new threats, technologies, and industry standards.

Just as a fashion designer ensures their red carpet creations are both stunning and structurally sound, we craft websites that are both visually impressive and secure. Like the high-profile security measures protecting A-list celebrities and priceless jewelry on the red carpet, such safeguards also keep the focus on your products or services, where it belongs.

A website can’t be great if it’s not also fundamentally secure.
