Red Team
A simulated cyberattack on your whole organisation.
Our Red Team engagements go where compliance tests don’t — social engineering, OSINT, on-site activity, and network intrusion — emulating the APT groups most relevant to your industry. Scenario-based and goal-oriented, they measure not every vulnerability, but whether a determined attacker can reach what matters.
Social engineering + OSINT
Known APT emulation
Ends in purple teaming
The challenge & the solution
Compliance tests tell you what’s patched. A red team tells you what’s reachable.
The challenge
Testing the whole picture
Organisations need to validate threat response and detection, social-engineering resilience, and internal monitoring — and to know which real compromise paths exist across people, process, and technology. Most assessments only touch part of that.
The solution
A tailored adversary
We build each engagement around your specific threats, deliberately including the social engineering, OSINT, and on-site activity that compliance tests exclude — and demonstrate the ability to emulate the known APT groups that matter to your sector and risk profile.
How we do it · attack-surface mapping
Every engagement starts by seeing you the way an attacker would.
For black-box adversary simulation, our offensive team builds and continuously maintains a living map of your external assets — combining open-source intelligence and active reconnaissance with traditional penetration-testing techniques. Publicly available data, external infrastructure detail, and the security tooling you rely on are all enriched into a single, evolving picture of the target.
OSINT
Publicly exposed data, people, and infrastructure gathered without ever touching your systems.
Active reconnaissance
Direct enumeration and fingerprinting of external-facing assets and defences.
Living target map
A continuously updated, enriched set of targets that guides the whole engagement.
Tactics, techniques & procedures
The adversary behaviours we reproduce.
Representative of the TTPs used in engagements — always tailored to the threat actor and objective agreed with you.
Tactic
Credential theft
Technique
Phishing with malicious links or attachments to harvest credentials.
Procedure
Targeted spear-phishing against specific individuals, followed by credential-harvesting tooling.
Tactic
Lateral movement
Technique
Exploiting known weaknesses in unpatched systems to reach further into the network.
Procedure
Escalating privileges and moving between hosts while staying below detection thresholds.
Tactic
Data exfiltration
Technique
Encrypting sensitive data and moving it out over covert channels.
Procedure
Using tunneling over common protocols to bypass detection and reach external infrastructure.
Tactic
Command & control
Technique
Maintaining communication with compromised systems to direct activity.
Procedure
Standing up resilient, covert C2 designed to persist and evade defensive monitoring.
Tactic
Evasion & obfuscation
Technique
Altering attack vectors to slip past antivirus and detection mechanisms.
Procedure
Changing signatures, behaviours, and indicators so activity is harder to detect and analyse.
Outcome
What it proves
Whether these behaviours are detected, how quickly, and how far an attacker gets before your team responds — the real measure of your defences.
Tenendo in-house development
Private tooling that keeps the emulation realistic.
Off-the-shelf tools are known to defenders. We continuously develop our own so we can emulate an arbitrary, current attacker.
/ 01
Private TTPs
An internal toolkit, constantly upgraded to stay ahead of the latest tactics, techniques, and procedures.
/ 02
Internal research
Ongoing research into new initial-access, lateral-movement, escalation, and persistence methods.
/ 03
Knowledge base
A curated record of techniques from previous engagements, ensuring consistent, repeatable success.
/ 04
On-demand TTP development
Offensive-development experience lets the team emulate a specific known attacker on request.
The attack lifecycle
From first recon to a debrief your blue team can act on.
01
Reconnaissance
External reconnaissance of the target organisation and its public-facing infrastructure.
external
02
Initial compromise
A range of attacks — from social engineering to exploitation — aimed at securing that first foothold inside.
foothold
03
Persistence, escalation & lateral movement
Expanding access and establishing persistence, moving deeper toward the objective.
internal
04
Achieving the objective
Leveraging the access gained to meet the goal of the test — data exfiltration or critical-infrastructure access.
objective
05
Debriefing & purple teaming
After the report, we debrief and give recommendations — and, with any remaining time, work alongside your blue team to build new detections and mitigations.
