Connected devices blend hardware, firmware, wireless protocols and cloud backends — and a weakness in any layer compromises the whole product. Our IoT penetration testing assesses the complete ecosystem the way a determined attacker with the device in hand would.
We extract and analyze firmware, probe hardware debug interfaces, attack wireless protocols and test the companion app and cloud API together.
Our IoT and embedded device penetration testing assesses the complete product ecosystem: extracted firmware, hardware debug interfaces such as UART and JTAG, wireless protocols like BLE and Zigbee, and the companion mobile app and cloud API. Aligned to the OWASP IoT Top 10 and Firmware Security Testing Methodology, we find hardcoded secrets, insecure update mechanisms and missing secure boot — the layered weaknesses that turn one device in an attacker's hands into a fleet-wide compromise.
Connected devices combine hardware, firmware, wireless protocols and cloud backends, and a weakness in any one layer can compromise the entire product and every unit in the field. Physical access to a single device often unlocks the whole fleet.
IoT penetration testing assesses the complete ecosystem the way an attacker with a device in hand would, from extracted firmware to the cloud API, before a flaw becomes a costly recall or breach.
Scoping & rules of engagement. We agree objectives, targets and boundaries for your iot device penetration testing, so testing is safe, authorized and focused on what matters to your business.
Reconnaissance & mapping. We enumerate the full attack surface in scope, building a complete picture before any exploitation begins.
Manual exploitation. Our senior testers chain vulnerabilities by hand — going far beyond automated scanners — to prove real, demonstrable impact.
Analysis & reporting. Every finding is triaged, risk-rated with CVSS and written up with a copy-paste reproduction and clear remediation.
Remediation support & free retest. We support your team through the fixes and retest the remediated issues to confirm they are genuinely closed.
Tools & techniques
We use hardware analysis tools to access UART, JTAG and SPI interfaces, firmware-extraction and analysis tooling, and BLE/Zigbee sniffing equipment, alongside companion-app and cloud-API testing. We extract and reverse-engineer firmware, hunt for hardcoded secrets, assess secure boot and update mechanisms, and attack the wireless and cloud layers. Testing follows the OWASP IoT Top 10 and Firmware Security Testing Methodology.

Every iot device penetration testing engagement concludes with a comprehensive, board-ready report and a working session to walk your team through it. Your report includes:
An executive summary with overall risk posture for non-technical stakeholders
Detailed technical findings, each with a step-by-step, copy-paste reproduction
CVSS v3.1 severity ratings and business-impact context for every issue
Prioritized, actionable remediation guidance your engineers can apply directly
A complimentary retest to confirm fixes and update finding status
A formal attestation letter for customers, auditors and compliance programs

Outcomes you can expect
After your iot device penetration testing, you will have clear, evidence-based visibility into your real security risk — not a scanner’s guesswork. You will know exactly which weaknesses an attacker could exploit, what the business impact would be, and the precise steps to fix them in priority order. Teams use our findings to close critical gaps, satisfy customer and regulator security requirements, and demonstrate due diligence to their board. With a complimentary retest included, you also get documented proof that the issues are genuinely resolved.
Engagement details & logistics
Every iot device penetration testing starts with a short, no-obligation scoping call to understand your goals, environment and constraints, followed by a fixed-price proposal and a clear statement of work. Most engagements are delivered fully remotely, with on-site work arranged where it genuinely adds value. Throughout testing we maintain an agreed communication cadence and escalate any critical, high-impact finding to you immediately rather than waiting for the final report. All work is performed under a signed NDA with strict data-handling controls, using safe, non-disruptive techniques and carefully coordinated rules of engagement to protect your production systems. On completion you receive your report and a walkthrough session, followed by a complimentary retest once your fixes are in place. Typical engagements are booked one to three weeks in advance, and urgent or pre-deadline testing can often be accommodated — just ask at hi@agentoffense.com.
Why organizations choose AgentOffense
Our iot device penetration testing is delivered by senior offensive-security engineers who test the way real attackers do — manually, creatively and with a relentless focus on proving genuine, demonstrable impact. Here is what sets our engagements apart:
Manual, exploit-driven testing that chains vulnerabilities the way a real attacker would, going far beyond what automated scanners can find.
Reproducible proof for every finding, with copy-paste reproduction steps your engineers can follow and independently verify.
Honest severity calibration so you invest in fixing what genuinely matters and avoid wasting effort on false positives and noise.
Clear, business-focused reporting that speaks to engineers and executives alike, tying every issue to real-world impact.
A complimentary retest included, so you get documented proof that your fixes actually close the attack path.
Responsible, collaborative delivery with a named point of contact and secure handling of all data throughout the engagement.

How much does IoT Device Penetration Testing cost?
Every iot device penetration testing is scoped and priced individually, so you pay for exactly the coverage you need — with no hidden extras. After a short, no-obligation scoping call we send a fixed-price quote, usually within one business day, with clear deliverables, a firm timeline and a complimentary retest included. The price of your iot device penetration testing depends on the size and complexity of the target and the depth of testing required, so you always know the cost up front before any work begins.
