The Cost at a Glance
The Certified Internet of Things Security Practitioner (CIoTSP) credential, offered by CertNexus and earned by passing exam ITS-110, has a refreshingly simple pricing structure compared with many security certifications. There is one mandatory expense: the exam voucher. Everything else, including study materials, practice tests, and any optional instructor-led training, is at your discretion.
| Cost Component | Amount / Status | Mandatory? |
|---|---|---|
| ITS-110 exam voucher | $367.50 USD (current) | Yes |
| Same-version retake | One free retake within voucher validity (normally 18 months) | Included with voucher |
| Prerequisite courses or experience | None required | No |
| Official or third-party training | Varies by provider | No |
| Practice exams and study aids | Varies by provider | No |
| Renewal (every three years) | Latest-version exam before expiration | To keep certification active |
The practical takeaway: if you are disciplined and already have some IoT or security background, your total outlay can be close to the voucher price alone. If you are newer to the field, budgeting a bit more for preparation is reasonable, and the sections below show where that money is best spent.
The ITS-110 Voucher Fee
The current voucher for ITS-110 is $367.50 USD. That single fee covers your first exam attempt and, under current policy, a free retake of the same exam version if you need it. Vouchers are typically valid for 18 months from purchase, which gives you a generous runway to schedule and, if necessary, retry.
What the Exam Looks Like for the Price
Understanding what you are paying for helps you judge the value. ITS-110 consists of 100 multiple-choice and multiple-response questions delivered over 120 minutes. That window includes five minutes for the candidate agreement and five minutes for the tutorial, so your effective working time is a little shorter than the headline figure. The exam is closed book. The current official page lists the passing score as 60% or 61% depending on the form, while the older blueprint states 60%; our CIoTSP passing score guide explains how to plan around that variation.
There are no formal education, experience, training-hour, reference, or prior-certification prerequisites. CertNexus recommends IoT and security familiarity, but nothing is enforced at registration. For a full walkthrough of eligibility, see CIoTSP requirements and how to qualify.
Pearson VUE Center vs. OnVUE: Does Delivery Change the Price?
You can sit ITS-110 either at a Pearson VUE testing center or online through OnVUE remote proctoring. Based on the information we have verified, the voucher price is the same regardless of delivery method, so your choice should hinge on convenience and test-day risk rather than cost.
- Testing center: Controlled environment, no worries about home internet or interruptions. The hidden cost is travel time and possibly transportation expense.
- OnVUE online proctoring: Test from home or office, saving travel. The tradeoff is meeting the online-proctoring requirements: a clean workspace, a working webcam and microphone, and a stable connection. Because the exam is closed book and no external-calculator permission has been verified, don't count on having extra tools at your desk.
If your home setup is unreliable, paying a few dollars in fuel to use a testing center can be cheaper than risking a disrupted session. Scheduling specifics are covered in our CIoTSP exam dates and scheduling guide.
What a Failed Attempt Actually Costs
This is where CIoTSP's pricing is notably friendly. Current policy includes one free same-version retake within the voucher's validity period, normally 18 months. In practice, that means a first-time miss does not automatically double your cost.
Even with a free retake, a failed attempt carries real costs: your time, the delay in getting credentialed, and the stress of reworking your study plan. Rather than counting on the retake, use it as insurance. If you want to understand how likely you are to need it, read how hard the CIoTSP exam really is and what we know about CIoTSP pass rate data.
Preparation Spending: Where Money Helps and Where It Doesn't
Because there are no mandatory training hours, preparation spending is entirely optional, and the right amount depends on your background. A candidate who already works with device management, network security, and IoT platforms may need little beyond the blueprint and practice questions. A candidate coming from general IT may benefit from structured instruction.
Free and Low-Cost Resources
- The official exam blueprint: Version 1.4 (issued 15 January 2019, modified 29 June 2022) lists the objectives you will be tested on. It costs nothing and is the best map of the exam.
- Vendor and standards documentation: Public guidance on IoT security, authentication protocols, encryption, and privacy principles maps directly onto the domains.
- Your own lab: A few inexpensive devices or virtual environments let you practice hardening, certificate handling, and network segmentation hands-on.
Paid Resources Worth Considering
- Practice questions: Because the exam mixes multiple-choice and multiple-response items, realistic practice helps you get comfortable choosing all correct answers. Our CIoTSP practice tests are built for exactly that.
- Instructor-led training: Useful if you learn best in a guided setting, but optional. Compare costs carefully against what you actually need; see our overview of CIoTSP training options.
Key Takeaway
Since the voucher is the only required fee, spend extra money only to close specific knowledge gaps. Take a practice test early, identify your weakest domains, and buy resources that target those gaps rather than purchasing a full course by default.
Matching Your Study Budget to the Seven Domains
The exam blueprint splits content across seven domains totaling 100%. Allocating your money and time in proportion to domain weight, adjusted for your own weaknesses, is the smartest way to avoid overspending. For the full breakdown, see our guide to all seven CIoTSP exam domains.
| Domain | Weight | Budget Implication |
|---|---|---|
| Securing IoT Portals | 29% | Largest slice; worth the most prep investment |
| Implementing Authentication, Authorization, and Accounting | 14% | Core security concepts; hands-on labs pay off |
| Securing Network Services | 14% | Network background reduces extra study cost |
| Securing Data | 14% | Encryption and data-protection fundamentals |
| Addressing Privacy Concerns | 12% | Often learnable from free public guidance |
| Securing Software/Firmware | 10% | Lab practice with update and integrity mechanisms |
| Enhancing Physical Security | 7% | Smallest weight; light review is usually enough |
Securing IoT Portals (29%)
This is the single largest domain, so it deserves the biggest share of your preparation. Expect to reason about how web and mobile portals, management consoles, and cloud interfaces expose IoT devices, and how to reduce that attack surface.
- Common portal weaknesses and how to mitigate them
- Secure configuration and access to management interfaces
- How portal security connects to device and data security
Authentication, Authorization, and Accounting (14%)
Know the difference between proving identity, granting permissions, and tracking activity, and how each applies to constrained devices and large fleets.
- Device and user authentication approaches
- Least-privilege authorization models
- Logging and accountability for IoT environments
Because Securing IoT Portals alone accounts for 29% of the exam, a candidate who skimps there cannot easily make it up elsewhere. If you only have budget for one targeted resource, aim it at that domain first.
A Short, Cost-Conscious Study Sequence
If you want a lean plan that avoids unnecessary spending, this sequence puts the heaviest domains first so you identify gaps early, while you still have time to address them cheaply:
Securing IoT Portals
- Study the blueprint objectives for the 29% domain
- Take a baseline practice test to expose weak spots
AAA, Network Services, and Data
- Cover the three 14% domains together, since concepts overlap
- Use hands-on labs where possible
Privacy, Software/Firmware, Physical Security
- Review the remaining 29% of content across three domains
- Run a full-length timed practice exam
For a fuller approach, our CIoTSP study guide expands this into a complete preparation plan, and the CIoTSP cheat sheet is a handy final-week review.
Renewal Costs After Three Years
The CIoTSP certification is valid for three years. The verified renewal route is to pass the latest-version exam before your credential expires. That means planning for another voucher purchase at whatever the then-current price is, which may differ from today's $367.50.
When you amortize the voucher over three years of validity, the annualized cost is modest relative to the career benefits. Still, set a calendar reminder well before expiration so you have time to study for any updated exam version, not just pay the fee.
Getting Your Employer to Pay
Many organizations that build or deploy connected products will reimburse certification costs, especially when the credential supports security responsibilities. IoT security touches product engineering, network operations, compliance, and risk, so the business case can come from several directions.
- Tie it to a project: Point to an upcoming IoT deployment, device rollout, or security review where the skills apply directly.
- Cite the domains: Showing that the exam covers portals, authentication, network services, data protection, privacy, firmware, and physical security makes the relevance concrete.
- Offer a commitment: Some employers want assurance you will stay; a simple agreement can ease approval.
- Ask for time, too: Study hours are a real cost. Requesting protected prep time is often as valuable as the voucher itself.
Roles where this credential tends to come up include IoT security engineers, security analysts working with connected devices, network and systems administrators supporting IoT environments, and consultants advising manufacturers or utilities. You can explore this further in our overview of CIoTSP jobs.
Weighing Cost Against Career Value
At $367.50 for a voucher with a built-in retake, CIoTSP is a relatively contained investment, and the lack of prerequisites keeps the total low. Whether it pays off depends on your goals: a candidate moving into IoT security from general IT gains a clear, vendor-backed signal of focused knowledge, while an experienced practitioner may value it more as validation than as a career pivot.
We deliberately avoid quoting salary numbers here, because credible, credential-specific earnings data is limited and invented figures would mislead you. For a thoughtful discussion of what the credential can and cannot do for earnings, read our CIoTSP salary guide and the broader analysis of whether CIoTSP is worth it. If you are still orienting yourself, start with what the CIoTSP certification is.
Key Takeaway
Your real cost is the $367.50 voucher plus whatever targeted preparation you choose. The free same-version retake and the absence of prerequisites mean you control how much you spend. Build your plan around the heavy Securing IoT Portals domain, practice with realistic questions, and schedule inside your 18-month voucher window.
