Episode 39 — Build Cross-Functional Relationships That Keep Security Embedded and Trusted
In this episode, we focus on something that affects security outcomes just as much as technology: relationships. If you are new to cybersecurity, it is natural to picture security as a specialized team that works in its own lane, but in most organizations security only succeeds when it is woven into the work of many other groups. That weaving does not happen automatically, because different teams have different goals, pressures, and definitions of success. Cross-functional relationships are how security becomes embedded rather than bolted on, meaning security is present early in decisions instead of arriving late to block them. Trust is the key ingredient, because when other teams trust security, they share information earlier, they ask for input sooner, and they treat security guidance as help rather than interference. By the end of this lesson, you should understand what it means to be embedded, how trust is built across teams, and what behaviors make security a partner rather than a roadblock.
Before we continue, a quick note: this audio course is a companion to our course companion books. The first book is about the exam and provides detailed information on how to pass it best. The second book is a Kindle-only eBook that contains 1,000 flashcards that can be used on your mobile device or Kindle.

Cross-functional relationships exist because security touches everything, but security does not own everything. Product teams care about features and user experience, operations teams care about reliability and uptime, engineering teams care about delivery speed and maintainability, and business teams care about goals, timelines, and customer outcomes. Security cares about reducing exposure and limiting harm, which can feel like a different mission, especially when security advice adds friction. A trusted security team learns the language of other teams and frames security needs in terms of shared outcomes, such as stable operations, fewer emergency disruptions, and safer customer experiences. When security communicates only in technical terms, other teams may tune out, not because they are careless, but because they cannot connect the message to their responsibilities. Relationships are the bridge that converts security intent into coordinated action.
Being embedded starts with showing up early and consistently, not only when something is wrong. A common pattern in weak security cultures is that security appears mainly during incidents, audits, or late-stage reviews, which conditions other teams to see security as a source of stress. A more effective pattern is predictable engagement, such as participating in planning conversations, being available for design questions, and building regular touchpoints where issues can be raised safely. This does not mean security must attend every meeting; it means security must be present in the moments where decisions are made that shape risk. When teams see security as part of normal work, they start to involve security without being forced. That is what embedded feels like: security input is expected rather than exceptional.
Trust is built through competence, consistency, and respect. Competence means security advice is accurate, relevant, and practical, not vague warnings. Consistency means security applies standards fairly across teams and does not change expectations unpredictably. Respect means security acknowledges other teams’ constraints and does not treat them as careless obstacles. When a security team gives guidance that is unrealistic, or changes requirements without explanation, trust erodes quickly. When security admits uncertainty and follows through on commitments, trust grows. Trust is also built by avoiding unnecessary drama, because exaggerated claims make people skeptical and defensive. Calm, evidence-based communication signals professionalism and makes other teams more willing to listen and collaborate.
A powerful way to strengthen cross-functional relationships is to understand what success looks like for the other team and connect security outcomes to that success. For example, operations teams want fewer outages and smoother recovery, so security can align around practices that reduce change-driven incidents and improve incident coordination. Product teams want faster delivery without customer harm, so security can align around early design input that prevents rework and reduces late surprises. Infrastructure teams want stable platforms, so security can align around baseline configurations and predictable patching routines that reduce emergency fixes. Business stakeholders want predictable execution, so security can align around risk-based prioritization that avoids random interruptions. When security can say, here is how this reduces your pain and supports your goals, security becomes a partner rather than a burden.
Cross-functional relationships also improve when security offers clear decision support instead of just rules. Many teams do not mind security requirements as much as they mind uncertainty and rework. If security can provide simple criteria for what needs extra attention, what is acceptable risk, and what requires escalation, teams can make decisions with fewer surprises. For example, if a team knows that changes touching sensitive data require a certain level of review, they can plan for it and avoid late delays. If a team knows that exceptions are possible but require compensating controls and an expiration date, they can work with security rather than fighting in hidden ways. Decision support feels collaborative because it helps teams move forward safely. Pure rule enforcement often feels adversarial because it blocks progress without showing a path.
Another relationship-building behavior is making security easier to consume. In many organizations, people avoid security not because they dislike safety, but because security processes can be confusing, slow, or inconsistent. When security simplifies its engagement points, like having clear intake paths for questions, predictable review turnaround times, and consistent guidance, teams are more willing to engage early. When security is slow or hard to reach, teams learn to proceed without security and hope for the best. That creates hidden risk and late-stage conflict. Embedded security means the secure path is the easier path, or at least not the hardest path. Achieving that often requires security to improve its own processes as much as it asks others to improve theirs.
Cross-functional relationships are also strengthened by learning how to disagree well. Security will sometimes say no, or at least not now, because some risks are too high. Trust does not mean always agreeing; it means being able to negotiate tradeoffs without losing respect. When security explains why a risk is high in plain terms, proposes alternatives, and acknowledges the business goal, disagreement becomes a joint problem-solving effort. When security simply blocks without explanation, teams may view security as arbitrary and look for ways around it. The ability to disagree with clarity and calm is one of the biggest indicators of a mature security culture. It keeps security credible while still preserving relationships.
Third parties also affect cross-functional trust because many teams work with vendors and partners directly. If security is perceived as a barrier to vendor onboarding or partnership, teams may try to bypass security review. The better approach is for security to collaborate with procurement, legal, and the requesting team to create predictable expectations for third-party access, data handling, and incident notification. When the process is clear and timely, teams can plan for it and vendors can respond more effectively. Security should also recognize that third-party relationships are often business-critical, so security input must be practical and risk-based rather than perfectionist. Trust grows when security helps teams choose safer options and negotiate better terms without derailing legitimate business needs. That is how security becomes embedded in business relationships, not just in internal technology.
A simple way to see whether security is truly embedded is to look at how often security is invited into conversations before major decisions are made. If security is mostly informed after decisions, relationships are weak or trust is low. If security is asked early, teams likely believe security will be helpful and will not create unpredictable delays. Another indicator is whether teams bring bad news early, such as admitting a control gap, reporting a near-miss, or flagging a risky dependency. People do that only when they trust that the response will be constructive. When teams hide issues, it is often because they fear blame, punishment, or unreasonable demands. Relationship building is therefore a risk-reduction strategy, because early information allows earlier intervention and smaller, safer fixes.
When you build cross-functional relationships well, security stops feeling like a separate department and starts functioning like a shared capability. Security priorities become easier to execute because teams understand them, trust the reasoning behind them, and can anticipate what is needed. Operational friction decreases because security engagement becomes predictable and supportive rather than surprising and disruptive. Incidents are handled faster because people communicate earlier and coordinate more naturally. Over time, trust turns security into a normal part of planning and delivery rather than a late-stage gate. That is what it means to keep security embedded and trusted, and it is one of the strongest foundations for durable security posture improvement.
