Firewalls, endpoints, servers, identities, applications, cloud environments and network equipment continuously produce events about what happens in the infrastructure.
The challenge is not just storing them.
Add Solution designs and implements SIEM architectures capable of centralizing, normalizing, enriching, and correlating telemetry to turn scattered events into context for security detection, investigation, and decision-making.
A Add Solution estrutura fontes, parsing, contexto, correlação e procedimentos para transformar logs em evidências úteis à segurança.
Arquitetura, execução e operação tratadas como partes da mesma responsabilidade.
Firewalls, endpoints, identity, servers, cloud environments and networks observe different aspects of activity. SIEM brings this evidence together to improve understanding.
The value lies not only in storing events, but in being able to use them when a question needs to be answered.
Integrations depend on the capabilities available. More sources do not automatically mean greater visibility: we need to collect what provides value for the use cases.
Syslog, agents, APIs, connectors, event forwarding, and other supported methods must account for volume, latency, availability, buffering where applicable, communication security, and capacity.
Assets, identity, geolocation, threat intelligence, criticality and inventory can enrich the data according to the architecture.
Centralizing data without structuring it may only centralize complexity.
Time, identity, asset, source, destination, behavior, and sequence help guide the analysis without automatically confirming an incident.
Correlation does not eliminate the need for analysis. It helps direct it.
Use cases connect risk, context, criticality, baseline, sequence, frequency, exceptions and priority.
Collecting everything is no substitute for defining what we want to detect.
Rules and use cases must reflect risk, context, criticality, baseline, sequence, frequency, exceptions and priority.
A good detection is not one that triggers more often. It is one that improves the quality of the investigation.
Tactics and techniques can support mapping, coverage, use cases, and gap analysis. Mapping rules to ATT&CK does not mean complete coverage.
The distinction prevents technical signals from becoming conclusions without investigation and process.
Something happened.
A condition deserves attention.
The evidence is analyzed.
The context confirms the need for handling in accordance with the process.
The timeline, user, asset, processes where available, source, destination, related events, context, history and searches help reconstruct the scope.
Investigation turns alerts into understanding.
Hypotheses, behaviors, intelligence, anomalies, and evidence can guide hunting. Indicators, reputation, and context enrich the analysis when available.
Intelligence adds context. It does not automatically turn an indicator into an incident.
Authentication activity, MFA, privileges, administrative accounts, sessions and changes add context when available.
PAM & Identity Security Zero Trust & Secure AccessEDR/XDR can share telemetry, alerts, users, connections, and responses, depending on the integrations available.
Endpoint Security (EDR/XDR)Firewalls, VPN, IPS, NAC, network devices, DNS, and proxy, where present, can contribute evidence.
Network Security & Firewall Network Access Control (NAC)Control plane, identity, workloads, networking, services, and audit logs vary by provider and platform.
CloudEDR provides deeper endpoint insight; XDR can correlate certain domains; SIEM centralizes, searches and correlates events from varied sources according to the architecture. They can coexist and integrate.
A tool generates signals. Operations turn signals into decisions.
Security, sources, events, detections, assets, identities, trends, and collection health must serve an operational purpose.
Retention, volume, storage, performance, search, and applicable internal, contractual, or regulatory requirements guide the architecture.
EPS, GB/day, retention, sources, data value, duplication, filtering, and architecture must be analyzed without relying on universal figures.
Telemetry must justify its operational value.
Collectors, connectors, agents, sources, latency, volume, parsing, storage, queues and failures also need monitoring.
We also need to monitor what monitors security.AI & Observability
False positives, new applications, assets, risks, behavioral changes, rules, sources, and priorities require review.
SIEM should not be treated as a project with an end date.
The assessment connects coverage, data quality, architecture, cost and process to identify concrete opportunities.
More than 15 years of experience connecting networking, firewalls, endpoints, identity, PAM, NAC, servers, cloud, observability and operations.
Environment, risks, and relevant questions.
Sources, assets, and identities.
Reliably receive telemetry.
Create a common language.
Relate events and context.
Identify relevant signals.
Reconstruct the history and scope.
Reduce noise and improve rules.
Track changes in the environment.
Technology centralizes events. Engineering determines which data matters, how it relates, and which questions they need to answer.
Vendors and platforms are covered on the technology pages. Here, engineering starts with the questions, the data and the investigation process.
Cybersecurity and Observability TechnologiesRespostas objetivas para dúvidas técnicas e operacionais que costumam surgir antes de um projeto.
Não. Coleta é a base; parsing, normalização, enriquecimento, correlação, detecção e investigação transformam dados em capacidade operacional.
Não. SIEM é tecnologia. Uma operação de segurança também exige pessoas, processos, procedimentos, integrações e capacidade de resposta.
Não universalmente. Eles podem coexistir e integrar-se, com fontes, escopos e capacidades diferentes.
Não. Um alerta indica uma condição que merece atenção; investigação e contexto determinam se existe um incidente.
Não necessariamente. Fontes e retenção precisam justificar seu valor para casos de uso, investigação e requisitos do ambiente.
