In cybersecurity, Secure by Design and Secure by Default are two key approaches to building safer systems. Here’s the difference:
- Secure by Design: Security is built into the product from the very beginning of development. This means addressing vulnerabilities during design, coding, and testing phases to create a system that’s inherently secure.
- Secure by Default: Focuses on providing products with pre-configured security settings that work right out of the box. Users don’t need to make extra adjustments to get a secure system.
Key Insights:
- Cyberattacks are escalating, with U.S. organizations facing nearly 1,876 weekly attacks in 2024 – a 75% increase from 2023.
- Recent incidents, like the Colonial Pipeline attack, highlight the need for stronger security practices.
- Secure by Design tackles vulnerabilities early, while Secure by Default simplifies security for users.
Quick Overview:
- Secure by Design: Best for long-term projects and new software development.
- Secure by Default: Ideal for consumer products needing immediate, hassle-free security.
Both approaches work best together, ensuring systems are strong from the ground up and ready to defend against threats from day one.
Why service providers should align to “secure by default” versus “secure by design”
What is Secure by Design
As cybersecurity threats continue to grow, adopting a "secure by design" approach has become essential for long-term protection. This philosophy shifts the focus by embedding security measures throughout every phase of the Software Development Life Cycle (SDLC), rather than treating security as an afterthought or optional feature. Let’s break down its core principles, key advantages, and what it takes to implement this approach successfully.
Definition and Main Features
Secure by design ensures that security is woven into the fabric of the SDLC – from the initial concept to the eventual retirement of a product. According to CISA:
"Products designed with Secure by Design principles prioritize the security of customers as a core business requirement, rather than merely treating it as a technical feature."
This mindset demands that potential threats are identified early, enabling teams to mitigate risks through thoughtful design, architecture, and proactive security measures. It also places responsibility squarely on technology manufacturers to maintain the security of their products and services throughout their lifecycle.
Some of the standout features of this approach include:
- Threat modeling: Identifying potential risks early in the development process.
- Shift-left security: Addressing security concerns earlier in the SDLC to prevent issues before they escalate.
- Defense-in-depth strategy: Implementing multiple layers of protection to safeguard systems comprehensively.
By integrating these strategies, secure by design helps create systems that are resilient and prepared to handle evolving cybersecurity challenges.
Benefits and Why It Matters
The secure by design approach offers both immediate and enduring benefits. By addressing security during the early stages of development, organizations can significantly reduce design flaws and the costs associated with breaches.
This proactive stance is especially critical in today’s threat-heavy environment. For example, in Q2 2023, organizations faced an average of 1,258 cyberattacks per week – the highest rate in two years. Additionally, 83% of companies report experiencing phishing attacks annually, while IoT malware attacks surged by 87% in 2022.
Secure by design not only mitigates immediate risks but also ensures systems remain resilient against emerging threats. It reduces vulnerabilities, encourages proactive security measures, and minimizes the likelihood of costly incidents. On top of that, it helps organizations meet regulatory requirements more effectively, reducing compliance risks.
Requirements for Implementation
Adopting secure by design requires a strong organizational commitment and significant resources. Leadership buy-in is crucial. As CISA explains:
"Every technology provider must take ownership at the executive level to ensure their products are secure by design."
This approach demands a cultural shift within organizations, fostering an environment where security is a shared responsibility. Open communication and collaboration across teams are essential to embedding continuous improvement and security practices into everyday workflows.
Invest in expertise. Developers need comprehensive training in secure coding practices and ongoing education about emerging threats. With up to 77% of organizations acknowledging gaps in their application security, there’s a clear need for stronger security capabilities.
On the technical side, implementation involves:
- Security checkpoints: Regularly reviewing security at critical stages of development.
- Zero trust models: Ensuring that no user or system is trusted by default.
- Continuous monitoring: Keeping a vigilant eye on systems to detect and respond to threats promptly.
Organizations should also define security requirements alongside functional ones from the very start. The DevSecOps approach – integrating development, security, and operations – ensures security remains a core part of the development process.
Other essential measures include:
- Conducting regular security audits and penetration tests.
- Establishing vulnerability management programs.
- Publishing clear vulnerability disclosure policies.
- Using automated security testing tools and tailored threat models during development to catch issues early.
While secure by design ensures protections are built in from the start, secure by default focuses on immediate out-of-the-box resilience – a topic we’ll explore in the next section.
What is Secure by Default
While secure by design emphasizes weaving security into every stage of development, secure by default takes a different route by providing products that are secure right out of the box – no extra tinkering required.
In essence, secure by default ensures that a product’s default settings are designed to prevent common exploitation techniques, requiring little to no effort from users to establish a baseline level of security. The Australian Signals Directorate‘s Australian Cyber Security Centre defines it as:
"Secure by Default refers to products and services that are secure to use ‘out of the box’, with little to no additional setup or configuration required to achieve an adequate security baseline."
This means vendors handle the heavy lifting when it comes to security settings, sparing users from the hassle of manual configuration. Features often include pre-configured options aligned with industry best practices – like secure logging, automatic authorization, and warnings when users attempt to adjust settings in ways that could increase risks. Secure by default also enforces strict access control, such as denying all access by default (only allowing approved connections), automatically enabling encryption for data in transit, and disabling non-essential or demo features. These built-in measures provide immediate protection as soon as the system is deployed, ensuring operational security from day one.
Benefits and Why It Matters
Pre-configured security settings offer a host of advantages, both for users and organizations. Secure by default reduces the likelihood of misconfigurations, especially for users who may not be cybersecurity experts, while also simplifying the overall user experience. As Srinivas Mukkamala, Former Chief Product Officer at Ivanti, puts it:
"Secure by default ensures a zero-day product is inherently secure out of the box. No complex setup is needed because core security features like secure logging and authorization are pre-configured."
For businesses, this approach translates into fewer security incidents, reduced downtime, and less frequent patching. It also helps organizations more easily comply with data security regulations. Beyond operational efficiency, secure by default can save companies from the high costs of fixing vulnerabilities after deployment, while also fostering customer trust and enhancing brand reputation. A notable example of this occurred in 2023 when AWS updated its S3 bucket settings to make them private by default – 17 years after S3’s 2006 launch. This simple change required users to actively opt in to make a bucket public, significantly reducing the risk of accidental data breaches.
Requirements for Implementation
To implement secure by default, it’s crucial to embed strong defenses into product configurations while ensuring users are well-informed about these measures. Clear documentation is a must, helping users understand the built-in protections and the risks of deviating from default settings. According to CISA:
"Secure-by-default products are designed to make customers acutely aware that when they deviate from safe defaults, they are increasing the likelihood of compromise unless they implement additional compensatory controls."
Organizations should also enforce the principle of least privilege, granting users and systems only the access they need to perform their tasks. On the technical side, this means automating secure configurations, avoiding hard-coded credentials, and using container images that have been thoroughly scanned for vulnerabilities and sourced from secure private registries. Shifting security left – addressing potential vulnerabilities early in the development process – and carefully managing third-party libraries and open-source components are also essential steps to maintain secure defaults.
A great example of secure by default in action comes from Cloudflare. In 2014, they introduced Universal SSL, which automatically provisioned SSL certificates for all customers, enabling HTTPS connections without requiring manual setup. Later, they developed an ML-driven WAF Attack Score to proactively defend against new threats without needing users to adjust configurations. By embedding security directly into their code, Cloudflare demonstrated how vendors can deliver continuous protection with minimal user effort. Unlike secure by design, secure by default prioritizes immediate, deployment-ready security.
Secure by Design vs. Secure by Default: Main Differences
After diving into the details of secure by design and secure by default, this section outlines their key differences to help shape your cybersecurity strategy. While both aim to strengthen security, they diverge in timing and focus.
Side-by-Side Comparison
The main distinction lies in when and how security measures are applied. Secure by design integrates protections into a product’s core from the start, whereas secure by default emphasizes pre-configured settings that safeguard users right out of the box.
Here’s a breakdown of how each approach applies security throughout the product lifecycle:
| Feature | Secure by Design | Secure by Default |
|---|---|---|
| Implementation Phase | Throughout the entire software development lifecycle | Post-development, pre-delivery to customer |
| Primary Focus | Embedding security into system architecture and components | Pre-configuring systems with secure settings as the default |
| Main Goal | Prevent vulnerabilities and eliminate broad categories of threats | Reduce the attack surface and mitigate risks from misconfigurations |
| Target Audience | Development teams and architects | End users and system administrators |
| Examples | Memory-safe programming languages, secure hardware design, threat modeling | Multi-factor authentication, removing default passwords, secure logging enabled |
| Investment Required | High upfront investment, often requiring leadership support | Lower initial investment, focused on configuration adjustments |
| Time to Market Impact | Can extend development timelines | Minimal impact on delivery speed |
As Threat-Modeling.com explains, secure by design involves "weaving protections into the very fabric of the product from day one", while secure by default ensures "sensible out-of-the-box settings" that protect users unless they choose otherwise.
Next, we’ll explore the advantages and trade-offs of each approach to help organizations make informed decisions.
Pros and Cons of Each Approach
Building on the comparison above, let’s take a closer look at the practical strengths and challenges of secure by design and secure by default.
Secure by Design provides robust, long-term protection by addressing vulnerabilities at their root. By tackling security at the architectural level, it can eliminate entire classes of threats and safeguard against attacks beyond the user’s control. Products built this way are inherently more resistant to common exploits, offering lasting security benefits.
However, this approach is resource-intensive. It demands significant investment and leadership commitment throughout the development process. Organizations may face delays in bringing products to market, especially if competitors prioritize speed over security. Adopting this method often requires a cultural shift, where security becomes just as critical as functionality and performance.
Secure by Default, on the other hand, is often more practical and easier to implement. It delivers immediate security benefits by locking down systems before they reach users. By pre-configuring secure settings, it minimizes risks without requiring major changes to development workflows. This makes it an attractive option for organizations with limited resources.
The downside is that users can alter these secure configurations, potentially introducing vulnerabilities. Unlike secure by design, which builds protection into the product itself, secure by default relies on settings that users might disable. Additionally, the complexity of modern environments can make it challenging for vendors to address every possible configuration scenario. Overly restrictive defaults may also frustrate users if security measures hinder usability.
Ultimately, both approaches wrestle with the same challenge: balancing security with usability and business goals. The best strategies often combine aspects of both, using secure by design for foundational defenses and secure by default to deliver user-friendly, ready-to-go protection.
When to Use Each Approach
Choosing between secure by design and secure by default depends on the unique context of a project and the specific needs of an organization. Here’s a closer look at when each approach works best and how they can complement each other.
Best Cases for Secure by Design
Secure by design is ideal for new software development projects. By embedding security measures during the design phase, organizations can reduce vulnerabilities and avoid the higher costs and complexities of retrofitting security later in the process. This approach is particularly effective for organizations that prioritize security as a core business value.
Long-term initiatives, especially those involving critical infrastructure or projects with evolving security demands, benefit greatly from secure by design principles. Building security into the architectural foundation ensures resilience against changing threats and minimizes the risks of severe security failures. While this method requires significant resources and executive commitment, the payoff is a reduced attack surface and stronger protection throughout the software’s lifecycle .
However, organizations should also weigh the potential competitive risks. If competitors prioritize speed over security, focusing heavily on secure by design could create a perceived disadvantage in fast-paced markets.
Best Cases for Secure by Default
Secure by default shines in consumer-facing products and applications. Its strength lies in providing out-of-the-box security, which is especially valuable in environments where users lack advanced IT knowledge. This approach ensures protection without requiring users to navigate complex configuration settings.
For organizations with fewer resources, secure by default offers a practical solution. It allows teams to maintain a balance between security and speed to market. Additionally, products designed for a wide range of users benefit from secure default settings, enabling individuals to adjust configurations as needed while maintaining a baseline level of protection.
That said, secure by default demands careful attention to user interface and experience design. Security settings must work seamlessly in the background to avoid disrupting the user experience .
Using Both Approaches Together
While each approach has its strengths, combining them creates a layered security strategy. As Yaron Galant, Chief Product Officer at Kiteworks, puts it:
"Secure by Default will be an uphill battle if a product is not Secure by Design. So Secure by Design is the foundation for Secure by Default. You need to have a good foundation."
This relationship is clear: secure by design establishes a strong architectural base, enabling secure by default configurations to work effectively. Michael J. Mehlberg, CEO of Dark Sky Technology, adds:
"These two strategies complement each other because, without Secure by Design, the software itself will be vulnerable to exploit regardless of how securely it is configured. Conversely, without Secure by Default, even the most securely designed and developed software can leave huge gaps that an attacker can exploit if not configured correctly."
By integrating secure by design during development, organizations can create robust systems. Secure by default then ensures users start with optimal protection, reducing the likelihood of misconfigurations and simplifying security for end users.
Georgia Cooke, a digital security analyst with ABI Research, emphasizes the importance of this combined approach:
"A vast number of vulnerabilities result from misconfiguration. The provision of a robust default setting mitigates the potential to introduce attack vectors. Naturally, Secure by Default is only of any use if the activated security is well designed and well implemented, necessitating Secure by Design practices to ensure minimal opportunities for exploitation."
Together, these approaches form a comprehensive framework for reducing risks. Rather than treating them as competing strategies, organizations should view secure by design and secure by default as complementary tools that address security challenges from multiple angles .

In today’s cybersecurity landscape, integrating security into both design and default settings is no longer optional – it’s essential. Secure by design ensures that security is woven into the very architecture of systems, addressing vulnerabilities during development. Meanwhile, secure by default provides ready-to-use protections, minimizing the need for user intervention and reducing configuration risks . Together, these approaches shift the responsibility for security from users to manufacturers, creating a more robust defense.
However, there’s no universal solution. Organizations must carefully assess their unique needs, risk tolerance, and operational environment to craft strategies that truly work for them. Cyber threats are not only evolving but also becoming more sophisticated, and with global cybercrime damages projected to surpass $6 trillion, the urgency to act has never been greater.
To meet these challenges, businesses must align their security efforts with market demands, regulatory requirements, and strong leadership. By adopting secure by design and secure by default principles, organizations can build comprehensive defense strategies that address vulnerabilities, adapt to emerging threats, and ensure business continuity in an increasingly hostile digital world.
The path forward is clear: combining these two principles is the key to tackling modern security challenges from all angles and maximizing protection in today’s cyber landscape.
