Why there is no estimate

Defender Security has a paid tier, but the listing publishes no price. Without one, any revenue figure would rest on a guessed price, so MRRLens shows none and leaves revenue out of its opportunity score.

Exploratory math, not an estimate: if it charged a typical price for its marketplace, active users × paid conversion × monthly price would give $3k–16k a month. Assumptions: active users: 80k; 0.5%–2.5% of active users pay; no public price: assumed $8.00/month, typical for this marketplace. Methodology.
