H33 is not a SIEM. Not a GRC tool. Not a blockchain. Not MPC. It is deterministic cryptographic replay infrastructure: post-quantum attestation, FHE-encrypted processing, and independently verifiable audit trails. Here is how it compares to the approaches you already know.
Not competitor comparisons. These are structural arguments explaining why entire categories of technology are architecturally insufficient — and what replaces them.
Security Information and Event Management platforms (Splunk, Elastic, Sentinel) collect and correlate log data. H33 produces deterministic cryptographic attestations.
SIEM platforms are fundamentally log aggregators. They collect events from disparate sources, normalize them, and run correlation rules to detect threats. The output is an alert or a dashboard. The fundamental limitation is that logs are mutable: an insider, a compromised agent, or a misconfigured forwarder can silently drop, modify, or delay events. When a regulator asks "prove this event happened exactly as recorded," a SIEM cannot provide mathematical certainty.
H33 produces attestations, not logs. Each attestation is a post-quantum signed, cryptographically chained record that binds an event to a specific point in time with mathematical certainty. The attestation is deterministic: given the same inputs, any independent party will derive the identical output. This property -- deterministic replay -- means that attestations can be independently reconstructed and verified by regulators, auditors, insurers, or opposing counsel without trusting H33, the customer, or any intermediary.
SIEMs detect threats. H33 proves what happened. They are not the same category. In practice, organizations use SIEMs for real-time threat detection and H33 for cryptographic governance evidence that survives legal and regulatory scrutiny.
Governance, Risk, and Compliance platforms (ServiceNow GRC, Archer, OneTrust) manage compliance through questionnaires, evidence collection, and workflow automation. H33 replaces questionnaires with cryptographic proof.
GRC platforms are fundamentally workflow tools. They manage the process of compliance: assigning control owners, tracking evidence collection deadlines, generating reports for auditors. The evidence itself is typically screenshots, policy documents, and self-attestation forms. The integrity of this evidence depends entirely on the trustworthiness of the person who collected it.
H33 replaces this trust-dependent evidence chain with cryptographic proof. Instead of asking "did you encrypt this data?" and accepting a screenshot of a configuration page, H33 produces a post-quantum signed attestation proving that the data was encrypted, when, with which algorithm, and what the result was. This attestation is independently verifiable by any party without trusting the person who generated it.
For organizations subject to multiple regulatory frameworks (SOC 2, ISO 27001, HIPAA, GDPR, PCI DSS), H33's attestation infrastructure provides a single source of cryptographic evidence that maps to controls across all frameworks simultaneously. One attestation can satisfy a SOC 2 control, an ISO 27001 control, and a GDPR requirement -- because the cryptographic proof is the same regardless of which framework is asking the question.
Blockchain-based governance systems use distributed consensus for tamper-evidence. H33 achieves deterministic attestation through cryptographic signatures without consensus overhead.
Blockchain achieves tamper-evidence through an elegant but expensive mechanism: distributed consensus among independent nodes. This creates strong tamper-evidence guarantees, but at significant cost: transaction latency (seconds to minutes for confirmation), throughput limitations (tens to thousands of TPS depending on the chain), monetary costs (gas fees), and dependency on network health and liveness.
H33 achieves equivalent or stronger tamper-evidence through a fundamentally different mechanism: post-quantum cryptographic signatures. An H33-74 attestation is tamper-evident because forging it requires simultaneously breaking three independent mathematical hardness assumptions (MLWE lattices, NTRU lattices, and stateless hash functions). No consensus mechanism is needed. No network participants need to agree. No gas fees are charged. The attestation is produced in microseconds, not seconds.
H33 does anchor attestations to public blockchains (Bitcoin mainnet, Solana) for additional timestamping evidence. But this anchoring is supplementary -- the cryptographic integrity of the attestation does not depend on the blockchain. If Bitcoin goes offline, H33 attestations remain independently verifiable. The blockchain provides an additional, publicly observable timestamp; the post-quantum signatures provide the actual tamper-evidence.
MPC distributes computation across multiple parties so no single party sees the complete input. H33 uses FHE to process encrypted data on a single infrastructure without seeing plaintext.
Multi-Party Computation is a powerful cryptographic technique that enables multiple parties to jointly compute a function while keeping their individual inputs private. The security guarantee is that no single party (or coalition below a threshold) learns anything about the other parties' inputs beyond what is revealed by the output. This is valuable for scenarios like private set intersection, joint analytics, or threshold signing.
However, MPC has significant operational constraints. It requires coordinating multiple parties who must be online simultaneously. Communication overhead scales with the number of parties and the complexity of the computation. Setup ceremonies may be required. And critically, most MPC implementations do not produce independently verifiable attestations of what was computed -- you get a result, but not a cryptographic proof of the computation.
H33 uses Fully Homomorphic Encryption (FHE) to achieve data privacy with a fundamentally different architecture. Data is encrypted under the client's FHE key before it enters H33's infrastructure. All computation occurs on ciphertext on H33's single infrastructure -- no multi-party coordination is required. The result is encrypted and can only be decrypted by the client. Additionally, H33 generates a post-quantum signed attestation proving what was computed, creating verifiable evidence that MPC typically does not provide.
RSA and ECDSA signatures are the foundation of today's digital trust infrastructure. Both are vulnerable to quantum computing attacks via Shor's algorithm.
RSA and ECDSA have served the internet well for decades. RSA's security relies on the hardness of integer factorization; ECDSA relies on the discrete logarithm problem over elliptic curves. Both problems can be solved in polynomial time by a sufficiently powerful quantum computer running Shor's algorithm. This is not a theoretical concern -- NIST has already standardized post-quantum replacements (FIPS 203, 204) specifically because of this threat.
The "harvest now, decrypt later" attack makes this urgent today, not tomorrow. Adversaries can record classically-signed data now and forge signatures once quantum computers are available. For audit trails, compliance records, and legal evidence that must remain trustworthy for years or decades, classical signatures are already inadequate.
H33 uses three independent post-quantum signature families: ML-DSA-65 (NIST FIPS 204, MLWE lattice-based), FALCON-512 (NTRU lattice-based), and SLH-DSA-SHA2-128f (stateless hash-based). An attacker must simultaneously break all three -- three independent mathematical hardness assumptions. Even if one family is compromised by a future cryptanalytic breakthrough, the remaining two continue to provide security. This defense-in-depth approach is why H33 signatures will remain trustworthy regardless of advances in quantum computing or classical cryptanalysis.
Traditional audits are point-in-time, sample-based assessments. H33 provides continuous, exhaustive, cryptographic verification of every operation.
A traditional SOC 2 or ISO 27001 audit follows a well-established pattern: the audit firm selects a sample of controls, reviews evidence for those controls during the audit period, and issues an opinion. The sample size is typically a fraction of the total population. The evidence is typically screenshots, configuration exports, and interview notes. The result is a point-in-time opinion that says "based on our sample, we believe the controls were operating effectively during the audit period."
This approach has served the industry for decades, but it has fundamental limitations. The sample may not be representative. The evidence may be selectively curated. The opinion covers only the audit period, not yesterday or tomorrow. And the audit report itself is an assertion by the audit firm -- there is no mathematical proof backing it.
H33 inverts this model. Instead of sampling, H33 attests every operation. Instead of evidence that can be curated, H33 produces attestations that are deterministic and independently verifiable. Instead of a point-in-time opinion, H33 provides continuous, real-time cryptographic evidence. Instead of trusting the audit firm, any party can verify an H33 attestation using publicly available tools. The attestation is the proof. There is no opinion layer between the evidence and the conclusion.
For organizations that undergo traditional audits, H33 attestations dramatically reduce audit preparation time. Instead of assembling evidence packages manually, the organization points auditors to the attestation chain. The auditors can independently verify every control, every event, every timestamp -- cryptographically, in seconds, rather than through weeks of manual review.
Eight dimensions across all six approaches. H33 is the only approach that is post-quantum secure, deterministically verifiable, and operates at cryptographic speed.

SIEM platforms collect, index, and correlate log data for threat detection and incident response. H33 produces deterministic cryptographic attestations that are independently reproducible and post-quantum signed. SIEMs can be tampered with by insiders, lose events under load, and cannot prove that a log was not modified after the fact. H33 attestations are cryptographically immutable and can be verified by any third party without trusting H33 infrastructure.
Blockchain achieves tamper-evidence through consensus among distributed nodes, which introduces latency (seconds to minutes), transaction costs, throughput limitations, and dependency on network health. H33 achieves deterministic attestation through post-quantum cryptographic signatures without consensus overhead. H33 processes attestations at microsecond latency with no gas fees, no block confirmation delays, and no dependency on external network participants.
MPC distributes computation across multiple parties so that no single party sees the complete input. This requires coordinating multiple participants, introduces communication overhead, and typically does not produce verifiable attestations of the computation. H33 uses Fully Homomorphic Encryption (FHE) to process encrypted data on a single infrastructure without seeing plaintext, then generates post-quantum signed attestations proving what was computed. No multi-party coordination required.
RSA and ECDSA signatures are vulnerable to quantum computing attacks. A sufficiently powerful quantum computer running Shor's algorithm can forge RSA and ECDSA signatures in polynomial time. H33 uses three independent post-quantum signature families (ML-DSA-65, FALCON-512, SLH-DSA-SHA2-128f) based on three independent mathematical hardness assumptions. An attacker must simultaneously break MLWE lattices, NTRU lattices, AND stateless hash functions.
Traditional audits are point-in-time, sample-based assessments that produce a snapshot opinion. H33 provides continuous, exhaustive, cryptographic verification of every operation. An auditor reviews a sample; H33 attests every event. An audit report represents the auditor's opinion; an H33 attestation is a mathematical proof. Audit reports expire; H33 attestations are perpetually verifiable by any party.
Run a live attestation. Verify it independently. Compare the output to what your SIEM, GRC, or blockchain produces. The proof speaks for itself.
