About Unsolicited Response

Unsolicited Response is Dale Peterson's show about the security of industrial control systems and operational technology. The interview is its core. Peterson introduces several guests as people his audience probably already knows. Rob Lee covers threats. He explains pre-positioning: intelligence agencies gather access to infrastructure so their leaders have options, even if that access is never used, and he uses the electric sector as his example. He cites the Telvent breach as proof that the practice is not new. He also pushes back on people outside the work who question the case defenders make for their security programs, and he closes by crediting the people doing the defending. HD Moore's conversation begins with his track record, from Metasploit to Rapid7 to the company now called RunZero. Peterson then quotes Moore's own memory that early on everyone hated Metasploit, and asks how he got through those years. Joel Langill's episode, streamed live on LinkedIn and YouTube and also released as a podcast, takes up training. Langill calls the SANS program a very good basis of knowledge. He objects to it being called a professional certification, though, because credentials such as the CISSP or PMP require experience in the field. Nor, in his view, does it teach security from an operational perspective. With Maggie Morganti the subject turns to people, including how comfortable some OT workplaces are for women and how to bring more women into the field. Then there is S4. The conference comes up repeatedly, and Peterson talks about it as someone with a hand in running it. In 'S4x25 Feedback & Review' he goes through attendee comments. He turns down all-day coffee rather than raise ticket prices, and he agrees that the first day lacked the energy of a main-stage kickoff and welcome party. The Long Conversation replay has the most unusual format here: two people start talking, and every ten minutes one of them is tapped on the shoulder and replaced. The topic is whether IT and OT should converge, integrate or stay separate. One participant argues that OT across solar, wind, power plants and battery storage needs its own specialized team. Where to begin depends on the listener. The Rob Lee interview suits anyone after threat talk, the HD Moore conversation suits an interest in security history, and the two S4 episodes show the conference from the inside. Several episodes open with the same line from Peterson: 'This is very exciting.'

Made for: Suits a listener who works in or near OT and ICS security and wants to hear practitioners argue about threats, training credentials and team structure in their own words. It also fits anyone following the S4 conference.

What sets it apart: Its close tie to the S4 conference sets it apart. Alongside the interviews, the feed carries a replayed relay-format session and the host's own review of attendee feedback, which gives an organizer's view of the OT security community.

In their own words

Dale Peterson interviews the innovators in ICS / SCADA cyber security as well as the top talent in related fields. It is the podcast for those who want more information similar to what is presented at the annual S4 event each January in Miami South Beach.

Long Conversation: OT and IT - Convergence, Integration, and Separation?Jul 30, 2025

A rotating 90-minute debate tests where OT and IT should converge, integrate, or stay separate.

OT and IT convergence plays out like a relay race, with a new speaker stepping in every 10 minutes across a roughly 90-minute discussion. That rotating format is not just a gimmick; it suits Dale Peterson's framing, because the central question keeps shifting as each person…

Unsolicited Response with Maggie MorgantiMar 13, 2025

A grounded conversation on OT security careers, product security, workplace culture, and women in ICS security.

Maggie Morganti's shift from about six years in OT security to senior director for product security at WorldPay gives the episode a useful question to work through: what changes when security is not a hard sell, but an expected part of the product.

S4x25 Feedback & ReviewMar 6, 2025

A candid S4 debrief where attendance data and room energy shape the next OT security gathering.

S4x25 works as a post-event debrief on what an OT security conference is trying to become. Dale Peterson thanks the 1,193 attendees and about 60 speakers who came to Tampa, then uses the numbers around 52% new attendees, 197 women, and 16.5% women as a plain-spoken way into…

Joel Langill On His New OT Security Training Class And MoreNov 13, 2024

Joel Langell argues for OT security training that turns risk assessment knowledge into judgment practitioners can use on the job.

OT security comes back into focus through Joel Langell's account of semi-retirement, family responsibility, and the work that pulled him toward the field again.
