How to start a Browser-Only Security for BYOD Contractors business: plan and growth
A client has ~50 offshore support contractors on personal Windows PCs working only in the browser (Google Workspace, Shopify admin, Zendesk); MDM doesn't apply and leak risk is real.
An owner can start “Browser-Only Security for BYOD Contractors” from a complaint people already posted. The offer, in one line: Session-level controls on copy, download and access logs for contractors on their own PCs, no MDM agent. It is for IT managers and BPO companies. Charge a B2B subscription, and test a price at $200 a month or more. Begin in more than one country. Buyers already talk about this in r/sysadmin. One thread gathered 21 votes and 40 replies across Sep 14, 2026 – Oct 14, 2026. Use that room to meet the first twenty buyers. Do not export it, and do not republish the posts. The idea, the evidence, and the market estimate on this page are free to read. Two paid prompts finish the job: one drafts the offer, the price, and a ninety-day calendar; the other drafts a month of conversations and proof. One credit unlocks both. A software specification is not on this site. When the company is the product itself, a single link further down opens the founder library.

Market size
An estimate, built from the bottom up: real customer counts × a realistic price. It shows the size of the prize, not a forecast.
TAM Total addressable
$114M a year
19,000 firms · 20% of US employer firms with 100–499 staff
SAM Serviceable
$34.2M a year
5,700 firms · sold direct
SOM Obtainable in 3 years
$168K a year
28 firms · 0.5% of the reachable segment in three years
What that means
28 firms at $500/mo = $168K ARR
Low confidence · estimated Oct 2026
How we estimated this
- Base: 93,300 US employer firms with 100–499 staff.
- Has the problem: 20% (assume 20% rely heavily on contractors).
- Revenue per firm: $6,000 per year ($500/mo).
- Reachable: 30% (sold direct).
- Three-year capture: 0.5% of the reachable segment.
TAM is customers with the problem × revenue per customer. SAM is the part a new business can reach. SOM is a cautious three-year share of SAM. The bars use a log scale. A share marked “assume” is our judgment, not a measurement.

Questions
How much money do I need to start?
Enough to talk to buyers and deliver the offer once. A service version can start with a written process and a way to take payment. A software version is a larger bet and is not required to test the price. The band to test is $200 and up.
How should I price it?
Test a price at $200 a month or more, charged as a B2B subscription. Raise it after three paid pilots, not before the first conversation.
Where do the first customers come from?
r/sysadmin is the clue. A related thread gathered 21 votes and 40 replies. Show up there, follow the room's rules, and ask for conversations. Do not scrape it.
Do I need to write code?
No. The prompts on this page draft a plan and a month of growth. Code is a later choice. The founder site linked once below is where the build document lives, if you want it.
A separate site sells the agent build document and can build the product. Read the agent PRD
A two-week build starts at $10,000 on that site, after a $1,000 scoping fee.
