HTTP proxy and monitor for viewing all HTTP and SSL traffic between a machine and the internet.
Small businesses need network sniffers software that works without a dedicated IT team: fast setup, transparent pricing, and enough depth to handle real operational needs without the complexity tax of enterprise platforms. The options below fit teams under 100 users most closely.
No product in this category matches the small business filter yet, so all 7 are listed below.

Transparent pricing with no "contact sales" gate, deployment measured in days rather than months, low administrative overhead, and enough automation to compensate for a small team. Avoid platforms that require dedicated admins or charge per-feature add-ons.
Pricing in this category varies widely by vendor and by what is counted (users, endpoints, or devices). Check each product's own pricing page for the current rate, and confirm which features sit behind paid add-ons before comparing totals.
Check the pricing curve rather than the entry price. Some products that are cheap at ten users become expensive at a hundred, and some free tiers end at a hard cap that forces a migration instead of an upgrade.
