A better way to buy security

  • You stop buying blind

    Competition surfaces the real price. On a single RFP the spread between quotes averages $24,500.

  • Hours, not weeks

    First quotes typically arrive within an hour. 75% of RFPs are awarded within 72 hours. Teams save four weeks of searching, diligence and chasing.

  • Every engagement traced

    Keep your scope, quotes, award and delivery in one place, with your whole team able to collaborate.

  • Neutral by design

    We don't run audits, and firms can't pay for placement. Each RFP lets qualified firms compete on the same scope, so you can compare real bids.

Security isn't an afterthought for TermMax. Thanks @procur3 for helping us run a clean RFP to find specialized Daml auditors ahead of our @CantonNetwork launch.

Procur3 fills a gap no other platform serves: matchmaking between protocols and audit firms. No rounds of calls just to get a quote — we compared multiple high-quality providers at once and weighed their strengths per project. We'll keep doing business with them.

FAQ

How does it work?
Select the security service you need and post an RFP with your scope, relevant GitHub repository and preferred start date. Make it public or invite firms privately, and require an NDA if the work is sensitive. Set a budget or let the market price the scope. The more useful detail you provide, the more relevant the quotes you'll receive.
How fast do quotes arrive?
First quotes typically land within the hour. Median time from posted RFP to selected firm is 48 hours.
Who sees my scope?
Only vetted firms matched to your language, chain and service tags, under platform confidentiality terms. Never public.
Can I bring my own security auditors?
Yes. They may already be on Procur3. If they aren't, you can invite them from the Suppliers section of your dashboard.
What can I procure beyond audits?
Contests, bug bounties, pentests, cloud infrastructure review, multisig and admin audits, monitoring and AML screening, incident-response retainers, tracing and compliance — any language, any chain, including your Web2 surface.
How are firms vetted?
Reviewed on entry for track record, credentials and engagement quality, then profiled by language, chain and specialisation, with reviews from completed engagements.
