The rivals identified
Nemeses(1)
Harmony Mobile Protect competes directly by offering enterprise-grade mobile threat defense that overlaps with DNS Firewall's mission to intercept malicious traffic and phishing attempts.
Differentiators
- Provides comprehensive on-device network protection that goes beyond simple DNS filtering to detect active threats
- Leverages massive enterprise-grade threat intelligence databases that far exceed standard consumer-facing DNS blocklists
- Offers deep integration with mobile device management systems for centralized security policy enforcement
Head to head
The target should pivot toward a 'privacy-first' consumer niche to avoid a direct feature war with Check Point's enterprise-hardened security suite.
Contenders(1)
This app competes by targeting the same mobile security segment, specifically focusing on network-level protection and man-in-the-middle attack prevention.
Same space(4)
NK Tunnel VPN competes for the same utility-focused audience by offering zero-configuration access to secure network tunnels.
Ultrasurf competes by offering advanced obfuscation techniques that appeal to users seeking to bypass network restrictions.
BlueWhale occupies the same utility space by providing encrypted connections and connection optimization for general mobile users.
NetBird competes for the same privacy-conscious user base by offering secure, encrypted networking and device posture checks.
Differentiators
- Utilizes WireGuard-based P2P networking for significantly faster and more secure data transmission speeds
- Includes sophisticated device posture checks that ensure only compliant devices can access the network
- Supports SSO and MFA integration, catering to professional users requiring higher security standards
New entrants(2)
Oneok VPN is a rapidly iterating competitor that focuses on protocol support and performance optimization for mobile users.
This newcomer enters the market with a focus on global server access and privacy, directly challenging the target's value proposition.

The outtake for DNS Firewall by KeepSolid
Strengths to defend, gaps to attack
Core Strengths
- MonoDefense bundle integration drives cross-sell revenue
- Multi-platform support enables household-level subscription adoption
Critical Frictions
- 3.8★ Android rating reflects stability regressions
- Aggressive trial-to-subscription prompts create high churn
Growth Levers
- Importable custom blocklists would address power-user gaps
- Wearable integration remains an untapped distribution channel
Market Threats
- Enterprise-hardened suites offer superior threat detection
- Established VPN competitors provide better performance-to-price ratios
What are the next best moves?
Rebuild connectivity logic because crashes are the top complaint → stabilize retention.
Sentiment analysis identifies crashes as the #1 driver of negative reviews.
Trade-off: Pause the KS Coin rewards feature development — stability is the immediate churn risk.
Audit trial-to-subscription flow because users report unexpected charges → reduce refund surge.
User complaints highlight confusion regarding free trial terms.
Trade-off: Same-quarter capacity available — no major lever displaced.
A counter-intuitive read
The app's stability issues are a greater threat to its market share than competitor feature parity, as users will abandon a security tool that fails to maintain a connection.
Feature Gaps vs Competitors
- Real-time behavioral threat analysis (available in Harmony Mobile Protect)
Key Takeaways
The app provides necessary network control but suffers from stability issues, so the team must prioritize crash fixes to stop churn before expanding the feature set.
Where Is It Heading?
Declining
The security market is consolidating around all-in-one privacy suites, and the app's current stability regressions leave it exposed to churn. If the team does not stabilize the connection, the user base will migrate to more reliable VPN-based alternatives by next quarter.
Connectivity regressions in the latest update erode the daily active habit, which compounds the rating drag already visible on Android.
Recent updates focused on stability, no feature expansion.
