An advisory unit built on real field experience. Not a management consultancy that has discovered COMSEC as a new service line.
The ICSL Group has been active in telecommunications and communications security since 1995. ICSL Consulting is the founding company and advisory unit for clients who need strategic assessments and independent advice.
Why we offer consulting:
In 30 years of fieldwork, we have repeatedly met decision-makers with fundamental questions about communications security who cannot find an adviser without a vested interest. ICSL Consulting fills that gap: independent, discreet and grounded in expertise.
ICSL Consulting operates according to the same principles as our entire company.
No customer names without express permission. No client lists. No marketing at our clients' expense.
We do not advise on behalf of manufacturers. We receive no commissions. Our sole obligation is to our clients.
We accept only engagements where we can deliver real value. Revenue does not come at any cost.
No detours through junior consultants. Your first point of contact is always at senior level.
From one of Austria's first internet providers to a specialist advisory and integration firm — telecommunications, telemedicine, cybersecurity, secure communications and applied AI.
One of Austria's first internet content providers and callback providers. Everything that follows — projects, developments and spin-offs — originates here.
Established Austria's first private PSTN operator as an ICSL spin-off: PTAG — running on Siemens EWSD, including interconnection with the state-owned PTT. Grew from zero to 35 employees and 1,100 business customers in three years — the only alternative telecoms operator in Austria at the time with positive EBITDA; successfully sold in 2000. Further telecoms ventures followed, including Best Telecom, A-Tel and Phoenix.
Established as a separate company — wholly family-owned to this day.
First secure communications systems for government bodies, businesses and VIPs — the beginning of today's COMSEC focus.
Developed and built a telemedicine business (TeleMed), founding vitaphone GmbH — an innovation leader with its cardiac monitoring phone, featured in ORF broadcasts; successfully sold in 2012.
ICSL GmbH & Co KG founded for the COMSEC business — later merged into today's ICSL GmbH: ICSL Secure Communications.
Biometric ID project launched, spun off in 2008 as AGSES: hardware-based tokens for authentication, access and secure transactions — subsequently manufactured under licence, including as the Bloomberg B-Unit.
Partnership launched with a Nokia spin-off for hardware-based encryption on standard phones.
Acquisition of the complete identity protection technology of Switzerland's AXSionics (a spin-off of Bern University of Applied Sciences) — including worldwide patents, licensed by Bloomberg among others.
Cooperation with Ardaco begins — Silentel joins the ICSL portfolio.
The first NATO-approved COMSEC solution in the ICSL portfolio.
Global hosting for secure communications solutions used by various government agencies.
For the first time in an EU country's history, all ministries and highest state bodies communicate with one another using encryption — across organisational boundaries, at classified level. Implemented by ICSL.
Assumed responsibility for secure communications solutions across EMEA — distribution, integration, workshops, training and partnerships.
ICSL Consulting and ICSL GmbH are brought together under a shared holding company in 2022/23 — family-run, just as on day one.
Bespoke development and integration of different cryptographic systems — tailored to individual customers.
Support for selected communications and endpoint security solutions — even when not purchased through ICSL. Because detailed expertise is often missing precisely where it is needed.
The first NATO-approved post-quantum solution for government agencies — also available as a service from ICSL.
