Census does not publish a separate category for cybersecurity and IT security firms; these figures use NAICS 541519, Other Computer Related Services, the closest official industry. The count moved +50.0% between 2022 and 2023 in South Dakota, against +10.7% nationally, so competition for the same buyers is growing faster here than elsewhere.
The industry is concentrated in Minnehaha County, Pennington County and Lincoln County, which together hold 50.0% of the state's establishments. For a firm selling into the same market, that concentration also shows where buyers already have the most vendors to choose from, and where a researched, specific first email matters most.

How cybersecurity firms should run cold email in South Dakota
Cybersecurity and IT security firms sell security assessments, managed detection, compliance readiness and incident response. These are the contacts, triggers and messages that make a first email relevant rather than generic.
Who to email
- CISO or head of security at larger firms
- IT director or CIO
- CFO or COO where there is no security lead
- Compliance officer
Signals worth researching
- Compliance frameworks being pursued, such as SOC 2, visible in job posts or trust pages
- Security or IT job openings
- New cyber insurance, audit or regulatory requirements in their industry
- Rapid growth in remote staff or locations
What to say
- Anchor the message in a compliance or business requirement, not fear
- Reference the framework or role you found
- Offer a scoped readiness review with a clear deliverable
What to avoid
- Scanning a prospect's systems and emailing the results unsolicited
- Breach-scare subject lines

How should cybersecurity firms approach cold email?
Lead with a business requirement the prospect is visibly facing, such as a SOC 2 effort, an audit, a cyber insurance renewal or a new regulation. Avoid fear-based messaging and never send unsolicited scan results, which damages trust and can raise legal concerns.
Who is the buyer for security services at mid-sized companies?
Many mid-sized companies have no dedicated security leader, so the IT director, CFO or COO often owns the decision. Where a CISO exists, they are the primary buyer, with compliance and finance involved in larger engagements.
Is cold email legal in the United States?
Yes. The federal CAN-SPAM Act permits commercial email to business contacts without prior consent, provided the message identifies the sender accurately, uses a truthful subject line, includes a valid physical postal address and a working opt-out, and honours opt-out requests promptly. CAN-SPAM applies in every state and preempts most state commercial email laws, except provisions aimed at falsity or deception. This is general information, not legal advice.
