Day in the Life of a Red Teamer: Thinking Like the Adversary
There’s a persistent myth about red team operators: that the job is all zero-days, glowing terminals, and cinematic “I’m in” moments. The reality is more interesting and far more human.
A day in the life of a red teamer is less about chasing flashy exploits and more about understanding how real people, real systems, and real environments fail under pressure. It’s about thinking like an adversary in a way that highlights critical junctions for organizations to defend against, leaving them stronger than before.
Not your typical path into cybersecurity
Red teamers don’t always come from traditional pipelines. In fact, some of the most effective ones don’t.
I didn’t grow up reverse-engineering firmware in my parents’ basement. My path into cybersecurity wound through the Marine Corps, retail and hospitality roles, and an academic detour spanning business, chemistry, and philosophy. That philosophy background turned out to be less of a side quest and more of a foundation, training the mind to question assumptions, challenge linear thinking, and examine systems holistically.
Cybersecurity didn’t enter the picture until my mid‑twenties, prompted by a single recruiter’s question: “Do you want to be a hacker?” What followed was a steep learning curve, a bootcamp, and countless hours of independent study, often learning more from hands-on experimentation and community resources than from formal certifications alone.
Today, with training far more accessible than it was even a few years ago, that kind of nontraditional entry point is becoming less of an anomaly and more of a signal: curiosity and adaptability matter as much as early exposure.
What red teaming actually looks like day to day
Every day starts the same way: checking communications. With global clients, urgency doesn’t follow a single time zone, and priorities can shift quickly.
From there, the work becomes highly variable. One day might involve planning a physical intrusion scenario. Another might focus on mapping an organization’s external attack surface. Others still may require crafting phishing or vishing pretexts, testing wireless networks, or attempting to pivot through a compromised enterprise environment.
The common thread is planning.
That planning is informed by a mix of technical and human-focused expertise. The work draws on exploit development when custom access paths are needed, but just as often relies on Human Intelligence (HUMINT) and counterintelligence-style thinking to understand how people, processes, and assumptions can be influenced or misused. Day to day, that means living in Kali Linux, leaning on Claude for research and analysis, and operating a mix of command-and-control frameworks and custom tooling depending on the engagement. The tools matter, but they’re always secondary to the mindset behind them.
Red team engagements are broken into phases - reconnaissance, passive analysis, active testing - and most of the real thinking happens before a system is ever touched. The goal isn’t to rush in, but to understand what should work, what might work, and what would look the most realistic if a real threat actor were attempting the same thing.

Signals, patterns, and the human element
In physical red team scenarios, success is often defined by invisibility. Can access be gained without interacting with anyone at all?
If interaction is unavoidable, attention shifts to patterns: environmental cues, employee behaviors, and opportunities to chain small, seemingly benign conditions into something exploitable. Proximity to public spaces. Maintenance workflows. Social expectations around helpfulness.
These moments often become “skill checks” for employees; tests not of intelligence, but of awareness and policy reinforcement.
In purely digital engagements, the signals are different but no less nuanced. Outdated software, misconfigured systems, exposed services, and inconsistent tooling coverage all tell a story about an organization’s security posture. Once inside, understanding detection patterns and defensive controls becomes critical. Getting caught too quickly isn’t just inconvenient...it can invalidate realism. Still, realism as a consultant differs from what an advanced persistent threat actor has access to, and this has to be emulated as closely as possible.
Choosing what not to exploit (and why that’s the hard part)
One of the least visible - but most important - skills in red teaming is analysis.
In any mature environment, there are dozens of potential attack paths available at any given moment. Some are flashy. Some are obscure. Some are technically impressive but operationally meaningless. The challenge isn’t finding something exploitable, it’s deciding what’s worth pursuing and what should be left behind.
There’s also a persistent fixation in red teaming on novel malware, silent post-exploitation techniques, and tooling designed specifically to avoid detection. While those approaches can be useful - and sometimes necessary, they don’t reflect how many real-world adversaries actually operate. Most advanced threat actors don’t spend weeks building bespoke malware; they buy what works or exploit targets of opportunity where security coverage is already thin.
From that perspective, an engagement that ends with “here’s how endpoint detection was bypassed and domain admin was achieved” only tells part of the story. Clients don’t meaningfully improve their security posture unless they understand what happens next: how that access could be abused, what it exposes, and how quickly damage could spread. The goal is to emulate realism beyond the obvious technical flaws.
Every potential path is weighed against a few core questions: How realistic is this for a real adversary? How likely is it to succeed without drawing attention? If it does succeed, does it meaningfully demonstrate risk to the business? Attack paths that rely on noisy, heavily fingerprinted tooling or highly contrived conditions may work in theory, but they rarely survive contact with modern detection stacks or scrutiny from a client trying to improve their defenses.
The most valuable findings tend to be the least glamorous: weaknesses that align with normal employee behavior, default configurations, or operational shortcuts taken over time. These are the paths that actual threat actors exploit because they’re efficient, repeatable, and difficult to notice until it’s too late.
Good red teaming doesn’t focus on the edge of technical sophistication, but rather, on what will actually happen given a motivated attacker.
Beyond “we got domain admin”
Many red team engagements celebrate a familiar milestone: achieving privileged access. Domain administrator. Root. Full control.
But that moment is rarely the conclusion; it’s the beginning of the most important questions.
Once high-level access is obtained, the focus shifts from can access be gained to what does that access truly enable? Can it be used to move laterally across domains or forests? Are backups segmented and protected, or could they be destroyed in minutes? Does privileged access expose unencrypted sensitive data, hard-coded credentials, or systems assumed to be “safe” simply because they’re internal?
These are the scenarios that determine whether an organization could survive a real attack or whether a single compromise could cascade into operational paralysis.
This is also where many traditional red team engagements fall short. A narrow focus on stealthy malware or novel exploit development can miss systemic weaknesses that have existed for years. Real adversaries don’t need cutting-edge tooling if an environment already provides everything they need.
That’s why assumed breach and purple team methodologies matter. They acknowledge a simple truth: detection failures happen. The real test is how far an attacker can go once inside and how quickly defenders can adapt.
The part no one talks about: writing
For all the technical depth involved, a significant portion of red teaming is writing.
Evidence must be collected meticulously. Actions must be justified. Findings must be explained in a way that survives legal review, executive scrutiny, and operational planning. A red teamer sets out to prove that these findings matter. Simply finding vulnerabilities isn't enough.
The process requires translating deeply technical findings into business risk: financial exposure, operational disruption, reputational damage, and human impact. It also requires telling a coherent story: how initial access was achieved, how trust boundaries were crossed, and why existing controls failed to stop it.
Without that narrative, even the most sophisticated operation is just a collection of screenshots.
Strong communication skills separate effective red teamers from merely skilled ones. The ability to write clearly, argue persuasively, and contextualize risk determines whether findings lead to action or get filed away and forgotten.
That translation work is also where trust is built. One of the most meaningful moments in this role didn’t come from a technical milestone, but from client feedback. After uncovering vulnerabilities in long-standing copiers and printers (devices that had been tested repeatedly over the years), a client reached out to say how much they appreciated the thoroughness, communication, and fresh perspective I brought to the table, and ultimately uncovered vulnerabilities that pen tests never did. Those human moments are often the clearest signal that the work is landing the way it should.
Skills that matter most
Technical competence is assumed. What differentiates strong red teamers is how they think.
Effective adversarial emulation requires stepping outside linear threat models and considering motivations that don’t neatly fit common categories like ransomware or data theft. Small vulnerabilities can lead to outsized impact; market manipulation, loss of employee trust, public perception damage, or cascading operational failures.
This kind of thinking is as philosophical as it is technical. It demands curiosity, creativity, and a willingness to challenge assumptions (both one’s own and the client’s). It also requires confidence to bring unconventional ideas forward and ask whether they can be tested safely.
Security controls are fallible. The job is to explore where and what that failure would mean.
Ultimately, the most indispensable assets are the people that have your back and can view a scenario from a different perspective. In complex environments, that shared perspective is often the difference between a shallow finding and a meaningful one.
So, what’s the job really?
For a non-technical audience, the explanation is simple:
A red team consultant is employed to think and operate like a real adversary. The aim isn’t disruption for its own sake, but prevention.
I like to joke that I essentially get paid to live-action-role-play (LARP) as a criminal and try not to get caught, all while documenting any weaknesses that are discovered so that companies can resolve the issues and prevent significant financial loss, destruction of company property, or the exploitation or manipulation of the employees that work for the company.
Some days that means quietly gathering signals and writing reports. Other days it means adapting in real time when a pretext is challenged or a detection fires unexpectedly. Occasionally, it means conducting work on-site, in unfamiliar places, navigating environments where human behavior matters as much as technical controls.
While the role has similarities across industries, what makes the experience unique is how it’s practiced. At LevelBlue, my role is intentionally designed to evaluate security across multiple layers at once (technical, physical, and human) rather than optimizing for a single predefined outcome. Unless a client explicitly requests a narrow objective, engagements are structured to surface interconnected weaknesses that might otherwise remain invisible.
This approach rewards curiosity and breadth of thinking. It encourages operators to look beyond “the exploit” and ask how small failures compound into systemic risk. It also creates space for collaboration - within the team and with clients - when unconventional threat scenarios or testing ideas emerge.
Clients don’t just want to know that something is vulnerable. They want to understand why, how it could realistically be abused, and what to do next. That depth of insight only comes from engagements that prioritize perspective over point-scoring.
There are also parts of the job that are simply rewarding on a human level. Traveling internationally for on-site red team engagements offers a chance to work closely with clients in their own environments, then step outside the operation and experience different cultures and social dynamics. Seeing how people work and think across different parts of the world adds another layer of perspective that ultimately feeds back into the work itself.
At its core, red teaming is about empathy - understanding how systems fail, how people behave, and how adversaries think, so organizations don’t have to learn those lessons the hard way.
