Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Government intelligence and law enforcement agencies need NSO Group's Pegasus platform for targeted lawful interception against encrypted communications where traditional signals intelligence hits a wall. The tool's three-decade operational history across 40-plus countries demonstrates sustained effectiveness in counter-terrorism investigations that NIST DE.CM and DE.AE monitoring cannot replicate alone. This is explicitly not for private sector buyers, smaller governments without legal frameworks for targeted surveillance, or any organization uncomfortable with the reputational and regulatory scrutiny that comes with deployment.
