No organization, large or small, is immune to cyber threats. When disruption strikes, it can throw your entire operation off balance—and the last thing you want is to break the news to your customers that you’ve been breached. At Nessit, our job is to keep your business protected and running smoothly 24/7, even when the unexpected happens. Our team handles the heavy lifting so you don’t have to worry about the behind-the-scenes technical details.
Whether it’s a client reporting that they clicked a suspicious link or our monitoring tools flagging a ransomware signature, our experts spring into action the moment an alert sounds. From swift investigation and containment to seamless recovery and post-incident review, here’s how we keep your business protected.
- Detection & Initial Response: Multi-Channel Alerting
- User self-reports: Sometimes the first clue is an employee calling to say, “I think that email I opened was a phishing attempt.” As soon as the Nessit team learns about a potential issue, we’re on it.
(Tip: The sooner you report “I clicked on something I shouldn’t have,” the faster our team can isolate any fallout. Even if the mistake seems minor, make the call. Early action is always cheaper and less painful than remediation.)
- Automated monitoring: Our suite of endpoint detection tools constantly scans for anomalies–suspicious file activity, unusual login attempts, or data exfiltration patterns. We’re not just watching for known malware signatures but for anything out of the ordinary that might need further investigation.
- Triage: Real Incident or False Alarm?
- Rapid validation: First, our engineering team digs into the data to figure out what is going on. We review telemetry–endpoint logs, network metadata, and logins from suspicious geographic locations–to determine if the alert represents malicious activity or a benign anomaly.
- Timely communication: When an incident has occurred, we notify your designated contacts about the source and severity, keeping everyone informed so you’re not left wondering what’s happening behind the scenes.
- Investigation: Scoping the Issue
- Gathering forensic data: If our tools detect a possible ransomware executable or credential-stuffing attempt, we immediately upload logs, memory snapshots, and user-context information.
- We verify geographic location anomalies: e.g., “Your CFO’s account attempted to login from Arizona at 3 am, but we know she’s in Maine.” If we detect an improbable login, we instantly lock down that account.
- Determining Spread & Impact
- Was it a single workstation? A server? Or multiple endpoints?
- We check backup integrity: do our immutable backups remain untouched? Is the ransomware strain new, or a variant of something we have mitigated before?
- Containment Actions
- Block high-risk geographies: Nessit’s baseline approach to all our clients includes blocking access from countries that frequently harbor malicious actor infrastructure–China, Russia, Ukraine, North Korea. And based on industry and risk tolerance, we may take additional precautions. For businesses like financial institutions that process large sums, tighter restrictions are necessary. Note: An effective strategy is a balance between security and user impact. While a bank may tolerate extra security layers, a lower-risk business might prioritize streamlined access. We always tailor our approach to maximize security while minimizing disruption.
- Quarantine infected systems: Any compromised host is immediately disconnected from the network. Even if it’s 2 am on a holiday, our on-call team is at the ready.
- Reset and harden credentials: if credentials have been phished or brute-forced, we reset passwords, reinforce Multi-Factor Authentication, and lock down any accounts that show signs of compromise.
- Neutralization & Eradication: Threat Response in Action
- Terminate malicious processes: our SOC team issues remote commands to kill any active malware. We pushed updated blocklists, preventing known bad IPs or hash signatures from reinfecting.
- Remove malicious artifacts: infected files get wiped. Persistence mechanisms (scheduled tasks, startup entries) are reversed.
- Recovery & Restoration
- Immutable, multi-tiered backups: Nessit follows the “Two Is One” backup philosophy, maintaining at least two independent backup layers, each air-gapped from your production network. That way even if one backup system is compromised, the other remains offline and untouchable.
- Rapid rebuilds: Once we’ve confirmed that the threat is neutralized, our team systematically rebuilds the affected servers and workstations, leveraging pre-validated backups.
- Post-recovery testing: Before handing systems back to your team, we run a battery of integrity checks to ensure the environment is truly clean.
- Communication and Stakeholder Updates
- Throughout recovery, we keep your leadership team and IT staff in the loop. Our real-time status reports will let you know which systems are back online, whether sensitive data has been exfiltrated, and the estimated timeline for full restoration. We know that transparency is vital, and frequent, clear updates help everyone breathe easier.
- Post-Incident Analysis & Future Prevention
- Root cause identification: Once systems are restored, our engineers perform a deep dive that includes the following:
- Entry point analysis: How did the attacker get in? Was it an end user error or a technical problem? A compromised VPN credential, phishing link, unpatched server?
- Lateral movement audit: Where else did they attempt to go, even if they failed?
- Detection gaps: Did monitoring miss the initial activity, and if so, why?
- Strengthening Defenses
- Policy enhancements: Maybe we need to enforce stricter MFA rules and education about password management. Maybe we need to add additional geoblocking for IP ranges that rarely have legitimate access.
- User-level restrictions: In cases where a single user accidentally clicked a bad link, we’ll work with you to impose limitations like restricting admin privileges or applying stricter device compliance checks. (Studies show there is an 80% chance the user at fault will get breached again.)
Why Work with Nessit?
- 24/7 Human-Led Response: Our analysts don’t sleep when you sleep. The moment a threat is detected–whether from your call or our detection tools–real people are investigating, not just automated scripts.
- Proactive Threat Hunting: We don’t wait for alerts. Our security experts comb through logs for subtle signs of lateral movement that automated tools might miss.
- Customizable Security Strategy: We evaluate your individual business needs to determine the right balance of user convenience and security.
- Post-Incident Partnership: After the immediate fire is put out, we conduct thorough postmortems, recommend policy changes, and shore up any weak links.
